You need to act quickly and paint the bumper within a limited time. These have a short time window for adhesion. These promoters help open the pores on the plastic so that applying coats of paint becomes easier since it'll adhere to the plastic surface faster.īut adhesion promoters have problems too. The need for plastic adhesion promoters is agreed upon by many. So, the best thing to do when using the solvent one is to wipe quickly before the absorption starts. These professionals recommend the solvent-based cleaners despite them getting absorbed. But it seems professionals or leading manufacturers suggest to not use the alcohol ones because they flash off and barely do any cleaning. In theory, one would choose the alcohol-based one. On the other hand, the alcohol-based wax or grease removers don't get absorbed into the plastic. Usually, traditional wax or grease removers are solvent-based cleaners, and this solvent gets absorbed into the plastic quickly. When choosing a wax or grease remover, you can either choose cleaners between solvent-based or alcohol-based.

The professional wash booth even blow-dries the part so that it removes both water and any dirt on the parts.Īlong with the detergent wash, there’s a special paste that some car workshops like to use to help abrade the plastic. Some manufacturers or professionals have their own automated washers that cleanse the parts with hot water and a special detergent. The next step is to clean the bumpers after the sanding is over. The good thing about these mole release agents now is that they are water-based and not wax-based. Although there are many mold release agents, you can find in shops nowadays. This happens because the overdoing of power sanding made the heat friction increase so much that it melted the plastic flat again.Īnother disadvantage of over-sanding is the release of mold on the plastic. In this case, when you're done sanding, you'll see very visible and obvious scratches, but after a while, it flattens out. If that happens then, any coat of paint will follow those lines and keep the “hairing” visible. However, if you sand too much, the plastic might split and melt and have thin lines that look like hair strands. Even if you do some scuff sanding by hand, it still provides a better result when you paint.Īnother advantage of sanding before painting is that it provides more clean areas to paint on and more places for the paint to cling onto. Because of sanding, the surface area doubles and makes it possible for fresh coating to stick over the old coating in the most effective way. The sanding is needed to create friction from heat so that the plastic becomes somewhat of a heat sink since it absorbs heat and softens.įor this, you can use an orbit sander that has a dual-action. Now that you have your bumper ready, the first task you need to perform before you move on to the painting steps is the sanding of the plastic bumper.
