Following my question on http://lumberjocks.com/topics/37986, if I get paint mixed at the big box store, most likely it will be latex paint.
Can i use this paint to spray paint a plastic surface?
I already primed this surface both with a “plastic” and ‘metal” primer.
Will it adhere or will it just peel after a while?
Thanks

Go to a decorating center, or paint store and have them mix you some enamel.
Nearly everyone has the computerized color matching capability these days.

seems to me that if it peels, it will be the primer’s fault, not the top coat.

Paint doesn’t adhere especially well to plastic in general. It
will stick, but it will scratch off easier than it does with metal
or wood.

Like Loren said, paint doesn’t really enjoy sticking to plastic surfaces. Since it seems like what you’re painting isn’t going to be flexing much or be exposed to high heat or outdoor conditions (am I right?), then you could use what you are wanting to use.

Prep is going to be key here though (as with any paint job). I’d scuff the plastic first. Treat it with plastic adhesion promoter (like Bulldog). Then hit it with a coat of primer made for plastics. Then paint. Make sure the surface is completely clear of waxes/greases by using a prep cleaner (there are several at the different autoparts stores).

A lot of paint jobs fail either due to poor preparation or using the wrong product in the wrong environment.

Rustoleum makes a rattle can labeled for use on plastic. I have used it on PVC pipe with no primer and no prep and been happy with it.

Thank you for all the replies.
I already cleaned and primed the surface with the Rustoleum plastic primer.
I shall have some paint mixed tonight and I shall paint the covers tonight, God willing.
