Best Glue For Plastic Car Parts Buying Guide

Things to Consider When Buying a Glue For Plastic Car Parts

There are literally hundreds of glues for plastic car parts available. Therefore, it is easy to become confused and choosing the right product for your needs can be tricky. To get you up to speed quickly, check out our simple list of what you should consider when you are buying the glue.

  • How much do you need?

There are big gluing jobs and there are small gluing jobs! Think about the size of the plastic parts that you need to glue. Generally, adhesives are sold in quite small quantities so make sure that you have enough. You may need to get two packs to make sure that you have enough to finish the job.

  • How long do you need the shelf life to be?

It is likely that you will not use all of the glue in the bottle. Throwing it away is wasteful and expensive. Therefore, it makes sense to buy a glue that will last for some time so that you can use it again in the future. Some glues specify a shelf life and others will last longer if you refrigerate them. Most glues are at least supplied with a cap which stops them from drying out. The glues that are supplied as two chemicals that need to be mixed together tend to last longer because they don’t start to set until they are mixed.

  • The materials you want to stick together.

It is important that you make sure that the glue is suitable for the material that you want to stick. Remember that you may be sticking two different materials together and the glue must be compatible with both of them. The term ‘plastic’ is a generic term and there are many different types of plastic. Read the specifications supplied by the manufacturer.

  • Do you need to drill or sand it?

Sometimes, you need a glue to do more than simply stick things together. You may need it to act as a filler for plastic car parts. You may need to sand it, to drill into it or to paint it. Make sure that this is possible with the glue that you are purchasing.

  • Does it matter if it runs?

When you are working on a vertical car part, the last thing you need is runny glue. Perhaps some sticky tape or an adhesive that has a paste-like consistency would suit you better? Check out the description to see how runny the glue is.

  • How durable is it?

Glue that is used to fix plastic car parts needs to be durable. If it is being used on the exterior of the car, it must be resistant to water and must not break down when exposed to sunlight. It will also need to withstand the vibrations caused by traveling on a road surface and the engine running.

  • What color is it?

Color matching may be very important if you are using the glue on the exterior surface of your car or internally where it will be seen. Transparent bumper glue is excellent for this. Other glues set to a tan or black color and you may need to paint over them.

  • How long does it take to set?

Fast setting glue seems like a good idea. It helps you get on with the job quickly and this is important if you need to do other things like sand it. Some glue sets in around five minutes and can be sanded in 30 minutes. Other glue sets even faster. However, if you know that it is going to take you some time to correctly position a plastic car part, a slower setting glue may be more suitable. Some glues set very slowly but once you are happy with the position of the two surfaces, you can spray an accelerant to speed up the setting time and get the job done.

  • How strong is it?

This is an important consideration. All manufacturers claim that their glue is the strongest glue for plastic! It would not make sense for them to say that it was weak! However, others give a value for a specific weight or force that the glue can withstand. All glues will have a limit.

Application of Car Glue

Always follow the manufacturer’s instructions carefully when using automotive adhesive. The first step is to ensure that you have the right glue for the job. You will need to make sure that the two surfaces are clean and dry and do not have any old adhesive or debris on them – this will affect the strength of the bond.

Sometimes, you have to mix two chemicals together to form the adhesive but at other times you just apply it to one or both surfaces with an applicator. The thickness that you use will be specified in the instructions. Sometimes, you have the option of spraying on an accelerant to speed up the setting time.  Now you just have the challenge of holding the plastic car part in place whilst the adhesive sets. Of course, you could just sit and hold it but if the setting time is 30 minutes, this could become tiresome. A more practical option would be to use a clamp or some tape but make sure that these do not cause a mark on the car part.

Different Types of Car Adhesives

Your main options here are a permanent or a semi-permanent glue. The one you choose will depend on the type of job that you are carrying out.

If you are carrying out repairs to car trims or bumpers, you will need a strong permanent car glue that can withstand heat, vibrations and moisture. This type of glue is built to last.  It will be very difficult to get it off again if you change your mind. You could end up causing damage to your car.

For temporary jobs, you would do better to choose a semi-permanent automotive glue. One option for this is a double-sided tape. This type of product will form a strong bond and it can withstand the outdoor elements. However, you can also remove it when you need to and it does not leave a messy residue.

Adhesives in the automotive industry can also be categorized as plastic epoxy adhesives and anaerobic adhesives. Epoxy adhesives are very strong and durable and can bond materials together even if they are nothing like each other. The main ingredient in this type of glue is Epichlorohydrin. It forms a very hard layer when it sets and is highly resistant to heat, cold and water.

Anaerobic adhesives contain monomers. These are suited to bonding to metals. Therefore, they are commonly used to seal and tighten fasteners or gaskets. Another common application is in bonding electrical components. Anaerobic adhesives are resistant to chemicals including fuels and oils.

When you read the product description for adhesives, you may come across some other terms which describe the chemicals that have been used in the manufacture of the glue. These include acrylics, urethane, elastomer and silicone.

How To Remove Adhesive Residue

Not all jobs go according to plan and you may end up having to remove adhesive from plastic car parts. Also, it is important that you remove old adhesive before you make s new join because it will weaken the bond.

There are several ways in which you can do this. The method you choose will depend on how much adhesive needs to be removed, the surface that it needs to be removed from and what tools/materials you have at your disposal. Most glues will provide some information about how they can be removed. It is always wise to patch test a small area when you are using a chemical to remove adhesive as it can cause texture and color changes on plastic.

  • Cutting with a knife: You may be able to trim old car glue with a sharp knife – a craft knife is ideal. You have to be very careful not to damage delicate surfaces. Scraping very carefully with a blunt knife, spatula or old debit card can also be very effective but you need to watch the surface underneath.
  • White spirit or methylated spirit: This can be used on some materials such as glass but could damage plastic so take great care.
  • Upholstery cleaner: If there is adhesive on your car seats or carpets, you may be able to remove it with upholstery cleaner.
  • Special cleaning fluid: This may be provided to remove a particular type of adhesive or sealant.
  • Moisturizer or vegetable oil: You can do this by soaking a cloth in the oil and dabbing the glue. Allow it to soak in and then wipe the old car glue firmly with a clean cloth.
  • Make-up wipes: These can be a very quick and convenient solution to break down weaker glues and wipe away the residue in one action. Use the wipe to gently dab the glue patch in a circular action.
  • Vinegar: This can be highly effective at removing stubborn car trim adhesive from plastic surfaces. Soak the area generously with vinegar and then wipe it off.
