Removing Porsche primer

[Smallblock454]

That won't work. If you want get off that primer chemically, you'll destroy the ABS plastic.

If you want to have a dull black plastic look you can use something like black Plasti Dip: PLASTIDIP.EU ... The EU supplier of USA PlastiDip!

Also i have to say that it is no wonder that the paint came out bad if you put the mirror housings in brake fluid, lacquer thinner, oil-base paint thinner, denatured alcohol, and acetone. That will affect the primer and the later on paint will never come out perfect if it reacts with the things you've put on.

Thanks, Markus, but no, all the paint removal attempts came AFTER the spray painting.

I received two perfectly primered housings. How hard could it be to spray matte black paint, right? So I sprayed, but had a flaw, like a hair. So I sanded that part and sprayed again. This time it was a particle of dirt in a different place. Sand, spray again. Got runs or drips. Before I knew it, I had WAY too much paint on the housings.

Okay, so have to start all over again. Brake fluid has worked for me before, and does NOT affect the underlying plastic. But the brake fluid won't soften and remove the primer. I tell ya, this primer is like ceramic powder coating or something. It is hard as nails.

I looked on the Web, and the suggestion was to try rubbing alcohol on acrylic. No effect. So that can be added to the list of things I've tried.
