I have a T-bird -61. I am restoring the original seat trim panel. Managed to bond cracks etc. Now need to paint them, original paint is partially gone. I tested to paint them with Vinyl Dye from Larry's, color is right, but the finish is no good, becomes patchy. The vinyl dye does not seem to cover tint differences between old paint, bare plastic and the white epoxi adhesive.
Anybody got any experince of painting original seat trim panels?
Would for instance standard car touch up spray paint work?
Anybody know what kind of plastic the seat trim panel are made of, it is a hard thermo plastic, so much I can tell?

I've had good luck priming plastic with a light coat of Dupli-Color Self etching primer first then spraying with rust oleum specialty paint for plastics. Probably any paint after the primer would work well

there is a super vinyl/plastic paint out by krylon...i have used it on items from plastic to rubber tires and it works great...if they had a neutral color that you could use, that's the way i would go...if you are 'off' color, i would definitely prime with a plastic primer - maybe a model plastic spray primer or and epoxy primer...

Some feedback, I used plastic primer as suggested, the one I found at the local car paint store was U-pol 2032, 1K Plastic Primer, transparent.
I let it dry for approx. 20 minutes and then applied 1 comp car paint spray. It sticks real well and looks very good.
My interior is red, the coler I found to match best were 30% gloss (semi gloss) Lada 110 red (code 40038987)
