It is common for minor accidents to take place, which can lead to denting or breaking of your car parts. If the accident is minor enough, you do not need to go to an automobile repair shop to fix a part that you can take care of easily. It is quite simple to quickly fix your car yourself rather than spend money on doing this. However, the damage must be considered before you start fixing it by yourself. If the damage is something you feel you cannot manage, you need to get it repaired professionally.
Glues are very useful and handy but they will not hold your front bumper long-term.
If you are looking to fix or repair a small broken piece, read further to know what kind of glue is the best for your needs.
Most car parts are held together using screws and bolts, however automotive glue provides durability and is an affordable solution for broken parts. Glue for automotive plastic is used for repairing some exterior or interior parts of your car. When the need arises, you will need to use automotive glue. The glue you use to fix parts of the car needs to be strong and durable. There is a wide range of glues that fit the description and this article will provide details of several types of glue that we recommended. Spoilers and cladding are usually held together by glues or double-sided tapes.
Also, ensure that the adhesive you use is durable and can weather any condition the car is placed in.
This type of glue is used for automotive fixing and repairs because of its strength and durability. They are known as two-part adhesives because it consists of two types of glue, mostly epoxies mixed together to create a strong adhesive. When these adhesives are separate, they cannot be used for heavy-duty repairs but when mixed together, the chemical reaction creates a strong bond. The process is similar to making automotive body filler but epoxy creates a bond strong enough to affix two parts together.
Single-part adhesives are a no-fuss product that is quite easy to apply. The glue dries quickly through evaporation. When you think of glues, one-part adhesive is probably the first thing you think about as they are more commonly used. However, they are not as durable and robust as epoxy, and are usually used to glue together parts that belong to the same material.
Two-part and single-part adhesives are liquid-based glues but moldable glue or sticky putty, as it is known, is an excellent option to fix parts that are hard to reach. This kind of adhesive also dries quickly by evaporation and is flexible and resistant to shock. This glue is useful when you want to fix malleable plastics in the interiors of your car.

If you want something that goes along smoothly with your car trim, choose this product as it is more effective than double-sided tape.
Once the product dries, it is shock, heat, and water-resistant. It also provides good insulation and is resistant to different weather conditions.
This product also has a few disadvantages. If you need to affix plastic on another material such as metal, it is better to choose another glue on this list as the hold is not as strong. Some might also find that the application process is a bit tedious compared to the ease of application of other glues.

If you search for glues and adhesives for car parts, you will get a ton of results. It can get confusing to know which glue is best suited for your needs. This simple list will help you narrow down your search to what is best for you.
How much glue do you need?
When considering the amount of glue, you will need, take into account the size of the car part of plastic that you wish to bond. Most adhesives come in small tin containers of bottles, so purchase at least two if you are trying to bond a sizable amount of automotive plastic. Two packets of glue will suffice for most bonding purposes. Even if you think it is not necessary to buy extra, do so for future needs.
Ensure that you check the package of the adhesive for its shelf-life information. When buying glue, you will want it to last for a long time as you will not use an entire pack at once. However, most glues have a good shelf life and if there is no information on the packaging of the glue, refrigerate it so that it can last longer. Most adhesives also come with caps so that they will not dry out quickly. If you are looking for long-lasting glues, buy glues that come as two separate chemicals. These glues last longer than regular ones as they need to be mixed for the adhesive to work.
Before purchasing adhesives, know what kind of materials you want to bond together. Plastic is a general term for different kinds of plastic that are available, so make sure that the glue you buy will be able to affix different materials together. It is therefore advisable to read the specifications provided by the manufacturer.
Drilling and sanding:
Your glue should be able to withstand drilling or sanding as sometimes glues can be used as fillers for car parts instead of sticking together the parts. If you are planning to drill or sand the parts, purchase a glue that will be compatible with the process.
There are glues that are runny but you should avoid these runny glues as they do not work well for car parts. If you are unable to find a glue that is not runny, use a double-sided adhesive or tape that will be better suited for vertical car parts, especially. If you are unsure about the consistency, check the manufacturer’s specification or the product description.
When you are using glue on a car, the glue needs to be extremely durable. It also needs to be resistant to water and weather conditions like extreme sunlight on exterior car parts. A car will also vibrate constantly so it needs to be able to hold the surfaces together despite this.
The surface where you apply glue matters when you choose which color glue you want. If you want to bond outer surfaces or even interiors where the glue might be visible, use clear ones. Transparent bumper glue is excellent for this purpose. Other glue colors are tan or black, which you might need to paint over.
The time needed to set:
While fast-drying glue is the most feasible and non-time-consuming option, especially when you need to sand the car parts, too. Most fast-drying glues will set within a few minutes and sanding can be done immediately after. The flip side to this is that slow-drying glue allows you to position the parts together well before the glue sets. Once the glue dries you cannot shift its position, especially if it is placed wrong. Slow-drying glue gives you this option and once you finalize how you want to place the parts; you can use accelerating spray to speed up the drying process.
All glues are advertised and marketed as “strong”. We cannot possibly know which glue is the strongest out there but it is better to know the value of specific weight that the glue can hold. This will narrow down your choices while shopping for the best glue.
Before you begin the process of applying glue to your automotive plastic, you will need to double-check if the glue you have is the right one for the materials you will need to bond. Next, ensure that you have read the instructions on the packaging carefully. After you have the glue and the materials, wipe down the surfaces so that there is no oil, acids, remnants of old glue or dirt on the surface. If the surface has debris on it, it can affect the way the materials bond.
Depending on your type of glue, you will either need to mix chemicals to form an adhesive or you can directly apply to one or both of the surfaces. Again, check the specifications on the manufacturer’s instructions if you want to know the thickness required for firm bonding. Different glues have different drying times so if your glue sets slowly, use accelerant spray to speed up the process.
Holding the car parts in place is also an option but if you want to save time, use a tape or clamp to hold it together because some glues can take up to half-an-hour or more to set. Use the tape or clamp with care as it might leave a dent on the surface of your plastic.
Type of Adhesives for Cars
The two options for car adhesives are permanent or semi-permanent adhesives,
For car trims or any external work, use a permanent glue that is strong and durable as it should be able to withstand weather conditions such as extreme cold or sunlight. However, if you are fixing a spoiler that you may remove at a later time, using a permanent glue can be more harmful than good as it is difficult to remove. The effort to remove the glue is tremendous and it might cause damage to your vehicle as well.
Therefore, for temporary jobs, use a semi-permanent automotive glue. The perfect solution is using double sided tape adhesives as they are durable and flexible. It will also not take lots of effort to remove and can easily withstand harsh weather conditions.
Plastic epoxy epoxy adhesives and anaerobic adhesives are the two types of plastics that are used in the automobile industry. If you have two materials that are very different from each other, for example, metal and glass, epoxy adhesives is your best option as this adhesive can bond two different materials very well. This is due to the fact that the adhesive contains a material called Epichlorohydrin. This material forms a sturdy layer and is resistant to water, heat and cold.
On the other hand, anaerobic adhesives contain monomers which are best suited to bond metals. These are also useful for bonding electrical parts as anaerobic adhesives are resistant to chemicals, fuels and oils.
Other common materials that are a part of glues are acrylics, urethane, elastomer and silicone. You might find these when you read the product description of the glues.
Removing Adhesive Residue
The versatility of glue makes it easy for minor mishaps to take place while bonding materials. If this happens to you, do not fret. Take off the old adhesive first before applying new ones as it can result is low bond strength. Here are some tips you can use if you want to take off old adhesives:
First take into account the amount of adhesive that needs to be removed and what kind of material you are using and what kind of tools you are using. If you want to use a chemical to remove the adhesive, try it on a small patch of the plastic first so that you will know if any changes occur as it can change the color or texture of the material you are using it on.
Using a knife: Using a blunt or craft knife is ideal when you want to scrape off the adhesive from the surface. if not a knife, you can use a spatula or an old credit card to scrape off the glue. However, do so carefully so as to not scratch the surface underneath.
Spirit: Methylated or white spirit can be used on glass surfaces but it can be detrimental to plastic so you should use it sparingly and with care.
Upholstery cleaner: If you want to remove adhesive off carpets or other car parts, you can use an upholstery cleanser to remove it without hassle.
Cleaning fluid: Using a cleaning fluid especially ones formulated to remove harsh stains can be used to remove adhesives
Oil or cold creams: Swabbing the old adhesive with oil or body lotions and leaving it on it for time can help loosen the adhesive. Once it is loosened up, use a cloth to wipe it off the surface.
Make-up remover: If the glue is weak and easy to remove, do not pull it off as it can still leave some on the surface. Instead use makeup remover pads or tissues to wipe it off. If you do not have this, put micellar water on a cotton pad to wipe it off gently.
Vinegar: If the adhesive is stubborn and tough to remove, dab it with some vinegar so that it becomes easier to remove.
General Prices of Automotive Plastic Glues:
Most glues are within the $15 price range and are quite affordable. There are single-part adhesives that are used commonly for household repair purposes. Just because the price of these glues is low does not mean the quality is compromised. In fact, a lot of good quality glues fall within this price range itself.
If you are looking for a brand name, then price is going to be more than $15, around the $25-$30 price range. Do not go for high-priced glues if you are buying for a single purpose.

If you are fixing or using glue on automotive plastic for the first time, do not guess or pick up just any adhesive. Do your research on which plastic you want to mend, which glue is best united for the job and how to go about it. Once you have this information, look up different glues available either online or in hardware stores. Some glues might be extremely durable and strong but if they do not state that they are compatible with plastic/metal, do not use it as it can damage the material. If you need expert advice on which adhesive to use, visit your local automobile repair shop as they will probably have an adhesive that goes well with metal/plastic.
The shelf life of most adhesives is between 6 months to 12 months. Few brands can also last for two years. Note that shelf life of an adhesive reduces once it has been opened. If you feel like the glue is not going to be used for a while apart from your project, buy one that has a cap or refrigerate it so that it lasts longer.
Yes, you can use plastic adhesives on other materials but just to be sure if the glue you have at hand is compatible with the material you want to work with, read the manufacturers guide or instructions. However, most adhesives adhere to materials like fiberglass, PV, coated metals, and aluminum.
Different glues have different setting times. Some glues might dry anywhere from 5 to 30 minutes while others need to be left overnight. Single-part glue is formulated in such a way that it dries fast so that it does not leak. Adhesive gel and putty takes long to dry and should be left overnight so that it sets well.
If you want to playback your home’s outdoor activity, you’ll need a camera with onboard video storage or cloud recording capabilities. Most cameras with recording capabilities have a built-in secure digital (SD) or microSD slot that allows for sufficient recording space. Once the memory card is full, you’ll need to delete footage or store it elsewhere. Some popular cameras automatically override expired videos, which may not be most ideal if you need to keep a video. On the contrary, some security camera providers offer cloud storage monthly plans to securely store videos on the cloud. You can easily access them anytime, anywhere by signing into your account on your mobile device or using a mobile app.
Glues come in different colors such as tan and black but also clear. If you are unsure about which color to use, buy a clear glue so that you can paint over it in the color of your choice later.
Tube-based epoxies and two-part epoxy putty are adhesives that can handle sticking plastic and metal together.
