I've a 1970 SS 396 El Camino that I'm restoring back to original; I just had the car painted in it's original Fathom Blue. I had all the trim refinished. I already restored the engine and it's bay including all electrical. The exhaust was replaced with Gardner exhaust. The car looks like it rolled off the factory floor. Restored the differntial; It even has stamped factory posi, which I think might be rare.

Ok, now that I've explained the work done so far, I can now explain my issue.

I hate the original blue interior. I don't think it works well with the painted Fathom Blue exterior. I would like to do the interior in parchment white; Likely it will reduce it's value, but I don't have a build sheet anyways.

Is it possible to paint origninal blue door panels parchment white and have it last. I've also a spare nice set of black door panels that I would rather use, in case I would like to put it back to blue. So, I'm guessing it's even worse to paint black to white. Does the paint adhere fairly well?

I could do the interior in black, but black is pretty common these days; I think a color of anysort is likely better.

I would keep the original blue panels and just put them away for now. You can buy reproduction white panels and not have to worry about the dye bleeding through. That way you have the best of both worlds. To answer your question, SEM makes a great set of dyes (plus prep) that will cover your panels but the blue will eventually wear though in time.

not a bad idea, but I do hate the aftermarket 70 door panels - they look so flat. But it would solve the problem
