I'm getting some painting done on my plastic rear bumper soon and the shop is not going to remove the bumper to prep and paint it, and not going to bake the new paint like they usually would. They say this is ok to do and it'll just take an extra day to dry sufficiently.

This shop says they can do all the prep and painting with the bumper in place, yet others say it can't be done well and they can't guarantee that the paint won't peel. I don't know who to believe.

Is there anything I should be aware of as far as drying or possible problems with paint peeling if it's not baked in the usual manner?
Thanks.

 

I have worked in a couple of different shops and i do prep and paint work. every car i've ever worked on in a shop has had the bumper(s) taken off to prep/paint. if the job is done right however there shouln't be a problem with peeling. if the paint is done right then not baking shoudn't be a problem, it just has to sit longer.
it's really a matter of how good of a job they do with prep/paint.
good luck

 

My partner & I have a shop where we do bodywork. We don't have a bake booth so we can't bake paint but most urethane paints dry in about 12 hours. Some may dry in 8 and some may dry in 16. It all depends on the product they use, but overnight at 70 degrees is normally ok. As far as the prep work, you can paint the bumper on the car but they will have to make sure that they scuff and clean all of the crevices like in between the bumper and the taillights. If they don't do this then a peeling problem may occur. I would ask them to remove it and maybe pay extra to get it removed and put back on, or maybe you can do that and just have them paint it. Most shops and paint companies have warranties for peeling. If you decide to have them keep the bumper on make sure that they will warranty it. Also remeber that with the bumper on the car it is a lot harder to get the proper amount of clearcoat or paint on the bottom even with the car jacked up. With the bumper off they will be able to get the proper amount on, not have to tape the car, and it will be easier to prep.

 

It must be the shat to be a painter. Just spray down some carz and get paid mad cash. Leave all the hard work the the preperz.
