Plastic Car Glue Buying Guide

From broken clips to buttons, having glue for car plastic trims readily available can save the day. Domestic glues are not up to the job of withstanding the punishment and environmental factors that a car will go through on the road. Specialized adhesives provide a stronger bond that is designed for automotive use.

To help you make an informed buying decision, we have put together the below buying guide regarding automotive adhesives.

Application of Car Glue

Glue for plastic car trims can come in a range of types that are designed for specific jobs. For example, glue for car headliners are normally in the form of an aerosol whereas spoilers require a thicker and stronger adhesive from a tube.

Ensure that the car glue you choose is up to the job of efficiently sticking plastic trim to your car. The wrong glue can become a nightmare to apply correctly or remove when you need to take the part off.

After you have applied any of the glue, its important that you allow it to settle before taking your car out on the road. We strongly recommend using tape to hold the car part in place (as shown below) to ensure that it sticks correctly.

Automotive Adhesive

Permanent or Semi-Permanent

When it comes to repairing items such as car bumpers or trims, you will more than likely require a permanent car glue such as the Tiger Seal. However, if you were installing a spoiler that at a later date you may want to remove, its not advised to use a permanent glue. Trying to remove a glue such as the Tiger Seal will not only require a serious amount of effort but may also cause damage to the vehicle.

There are many semi-permanent automotive glues available and our favorite is the 3M double sided tape. Once applied, it forms a strong bond that will be able to withstand the outdoor elements and many years. However, it can also be removed when you wish without leaving too much glue residue.

Before purchasing any glue you should decide on whether it is to be permanently stuck to the car or not.

How To Remove Adhesive Residue

The result of removing car parts such as spoilers, plastic trims and body kits is the tough residue left behind. Avoid picking the residue with your finger nails or over washing the area because this will cause damage to your paintwork.

We highly recommend investing into a rubbing compound that will easily remove any residue. Most will require use of a car buffer but this will be the safest method of removing the residue. If it is failing be removed, you may require light sanding and then polishing again.


Gluing plastic car parts back in place is far easier than you would expect. There are now hundreds of automotive adhesives that will be able to withstand testing weather conditions and other outdoor elements. All of our recommendations are the best for specific tasks and are easy to apply without being too messy.
