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. 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. 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. Other glues set to a tan or black color and you may need to paint over them. 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.
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. 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. 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. 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. It will be very difficult to get it off again if you change your mind. For temporary jobs, you would do better to choose a semi-permanent automotive glue. 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. 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. Not all jobs go according to plan and you may end up having to remove adhesive from plastic car parts.
