Sealing paint on a plastic object?

Question

I painted a small area of a plastic object with an all purpose paint and the paint seems to bond fine without a primer, however, the painted objects are stored where they bang against wood and I am constantly finding small spots that I have to touch up. Is there anything that can seal this paint on to take a little more abuse. They seem to fall victim just to light bumps and it is getting kind of annoying.

Yeah, I was too cryptic for no reason as to what the object was. I have (illegally) painted the orange blaze tip off some air soft guns (didn't want to mention it so I could avoid answers saying "well that is illegal," etc.). Anyways, the objects are air soft guns and the painted part are the orange blaze tips. I store the guns under my bed in a wooden drawer and when they bump against the wood they have a tendency to lose paint in small spots. This is a big deal to me because I use these guns as movie props so they must look as real as possible (without being real). Is there anything that can seal the paint and keeping it from doing this? Small bumps is all I really care about but it would be great if there was something to seal them against dropping, like I just accidentally did with one of mine, on a hard surface.

Answer 1

oil based paint mate is what you want, no primer required it will stick easily to most plastic

Answer 2

Knowing the type of plastic, and more importantly; they substance of the paint; will help determine any clear coat to apply.

Obvious in your Q is that it's too late to suggest Primer, and in many ways the primer and paint would still be just as likely to endure abuses.

Beyond those; is the question of WHAT the object is; and it's purpose.

Answer 3

Surfaces to be painted generally need to be "keyed up", or sanded lightly, to enable the paint to adhere better. Also, a suitable primer is reccomended, for the paint to bond better. Plastics generally require special primers, depending on the type of plastic and paint being used.

Answer 4

You can try one of the sealers by Krylon spray paints. They will adhere just fine to other paints and will give a protection above and beyond the regular paint that is on currently.

You can choose anything form matte finishes to high gloss. If you want a painted on finish, use a varnish which will dry clear over your paint and will give protection just like it does to things like kitchen cabinets.
