There is some discussion about new aftermarket covers needing to be baked to sweat out the mold release agents before any work is started. You guys have any knowledge of this? Maybe you bake them anyway. Word is 140deg for 4 hours.
All OEM covers used to have to be baked. I know some have changed their methods and no longer need to be baked. I know Toyotas are this way.
Don’t see hardly any raw A/M covers. I think I have seen 1 or 2. There would be no need to bake one with primer on it.
I know if I had to bake a bumper in the booth for 4 hours the cost of gas would far outweigh the the savings on price.
These guys might be buying the $50 ones from Timbuktu.
When I went to school we were taught to really watch out for it. It’s definitely not a new phenomenon. We were taught to bake them really well and wash them with soap and water as hot as we could stand to sweat the agents out of the plastic. I’ve personally never had a problem with bumpers which leads me to believe that most companies are taking steps at the factory to get rid the contamination from these agents. But they really drilled it into our heads every year at tech school that you have to get them out of there. I imagine the cheaper aftermarket companies would be the worst. But thats my own speculation
I am about to replace my wife’s Toyota Camry rear bumper. I dont have any way of baking it. Should I take it to a shop and have them bake it for me, or just run with it as is?
Unless the bumper is raw plastic (most I come in contact with aren’t) I wouldn’t worry to much. I’ve done some Toyota ones that were but I don’t recall whether they are OEM or not, Unless you really cheaped out on the bumper I wouldn’t worry about it to much. You can do the hot soap and water wash if your paranoid.

In fact they recommend not to.
Worse case you can always sit them out in the sun for an hour or two.
Thanks…
I dont have a shop that I can order parts through so who would you guys buy parts from if you were me?
Need front, rear, and side skirts for a 07 Camry SE.
I know BASF’s recommendations are raw plastics only need to be pre-baked if you plan on baking to cure after painting.
Have been refinishing raw covers and never have any adhesion problems , we wash them down with anti stat and then wash with soap and water. Next apply the correct adhesion promoter, then seal the cover, and apply base coat and clear. Been doing it that way for years and never have had a peeling problem. Sikkens has an all plastic reducer to mix in the sealer to adhere to any type of raw plastic, ABS or polypropylene. Never baked one in twenty years. We guarantee our work for the life of the car. I actually prefer raw covers, they are easier to prep.[color=#0000FF][/color]
We used to have the all plastic reducer for color build sealer but it has been discontinued.Now it is called all plastic adhesion promoter.You must first mix your color build sealer 3:1 with Elastoactif,then mix your colorbuild E.O.A mixture with colorbuild sealer hardener and all plastic adhesion promoter 100:25:35 #5 mixing stick.The updated version seems to work much better,we have had problems in the past with aftermarket primed bumpers.
