In the past I have painted white plastic panel-joining hardware black, only to have the paint scratch and flake off during repeated use. Is there a way to dye plastic prior to painting so that scratches don't expose the underneath color as prominently?

What type of plastic is it? There are some plastics that nothing will stick to.

Forget about dyeing the plastic, won't happen. Have you tried Krylon "Fusion" paint? This product bonds with the plastic piece.

FWIW

I have acctuly used Kyrloyn Fusion on several diffrent types of plastic, and found it to work fairly well. A few good coats on most plastics works fairly well, and if you do run into a chip or what not, a quick spray, fixes it. If fusion dosent work on the plastic you are using for whatever reason, you may just have to live with it.

I'm not sure what type of plastic it is.

I use Fusion on just about everything I build, and I will use it on the next project, but I thought the dye idea might work as an undercoat.

The only colorant I've found that won't scrape off of plastic is Sharpie ink.

Everything else is "iffy" at best.

Sharpie was my first thought. Can paint be applied over Sharpie ink?

Sharpie ink is basically a liquid styrene in an alcohol base. So, in a sense, you would be putting plastic on top of plastic, and then be back to square one, painting on plastic. I have been succesful with applying clear gloss sealer over Sharpie ink, but never tried to paint over the top of it. It has been very useful for outlining trim and such on my circusy kids show props.

Thanks, Stanyon. I'll give Kryon Fusion a try as the other acrylics paint I used get stripped off plastics so easily. I'll try the sharpie too.

Depeniding on the type of plastic.. You can use RIT to tint it.. (but not with the saturation you might want)..

There are dyes that do synthetics well:

that worked well on my kitchen utensils when I dyed some pants for Halloween.. (and it was a very saturated color too!) They're designed for Nylon and Polyester..

IT all depends on the type of plastic..

Assuming the paint was the same color as the Sharpie ink, this should not be a problem, IF the problem is the actual color of the plastic showing up through scuffed painted areas... in this case, white plastic under black paint. If the Sharpie can color the plastic black before the black paint is applied, scuffs won't show as easily.

You might also try using Kilz or a solvent to rough up the surface of the plastic, but of course you might want to try it on a test piece first to make sure the change in the finish doesn't bother you.

Also, as odd as it sounds, try soaking the plastic in a really strong solution of Kool-Aid in the appropriate color. It has amazing staining properties, and I have used it on a lot of odd things with some success. You want the kind that you sweeten with sugar, not the pre-sweetened stuff, and of course, you aren't adding the sugar to it either. I would recommend just enough really hot water to cover whatever you want to dye, and add the envelopes of KoolAid, mix, and let sit overnight.

Just a thought, but one that might come in useful for something else as well.

Cheers,

Pix

You may want to try the purple pvc primer, Ive used it on a few projects as a base coat and it seems to be holding up well. Other than that the Krylon fusion.
