    This is a question I asked on my Camaro site also:

    [quote]I am ready to start the prep process for painting on all my interior parts, plastic ones.
    I searched and got good info on cleaning and I will do all that but what I did not see or maybe I missed was if I am painting the parts that are now black and some blue to red what do I prime with or do I prime?
    I am shooting Sherwin Williams Ultra 5.0 and have Bulldog Adhesion promoter to use before I spray.
    I got it color matched to the interior vinyl parts, which are all new.
    I will use the same paint for my interior metal parts, dash, doors etc.
    It is a 67 vert.

    Thanks in advance.

    There was a discussion on painting PP recently.

    There also is some great info on FiberglassForums.

    what kind of plastic is it?

    I called the paint store and talked to them about it and after telling them what the label said and what my receipt said, they determined that the label on the can was wrong and what they mixed up was UIC or Ultra Interior Color w/ vinyl option.
    So that is what I have (I hope) and they faxed me a new TDS to go with what they say is in the can. They also said no primer is needed.

    To answer your question, I don’t know. It is what ever they made plastic parts in the 60s out of.
    I am also using this same paint on the metal parts in the interior. They told me it can be used for both.

    Thanks

    When I shoot mine all I do is scotch bright it, dx330, and use bulldog.

    You really need to find out. I would guess Urethane of some sort. Tough to say.

    paint is paint, but the different plastics adhere differently, and off-gas sometimes, and literally seem to sucrete oils other times……

    To be safe, sand it up good, blast it with solvent-based, anti-static plastic cleaner. let it dry, and do it again. spray plastic adhesion promoter, then epoxy primer, then whatever filler primer of choice if necessary to smooth out texture. The nastier the type of plastic, the rougher grit of sandpaper I would start with. If you don’t sand out the texture, it will be more pronounced than when you started.
