From what I have seen it's more of a semi gloss, probably a hard color to duplicate, I just did mine with the krylon fusion gloss black and it looks sharp, went on really nice, i guess i'll have to wait and see how it stands up, i've used that mar-hyde plastic and vinyl paint before and it seems to stick well to vinyl but not to the harder plastics, even with the primer.
also make sure the pieces you're painting are really clean, use dish detergent and water with a scrub brush, and let dry, i have learned from experience that harsh cleaning chemicals can produce, how they say "undesirable results"
I thought about painting the interior the same color as the outside but I wondered how bad the glare would be off the glossy dash. I am going to paint the outside red which I thought would look good on the inside too with black panels. I also saw were paddock sells black interior paint for the nova but I can't see how it would be any better than the appliance paint.
I have used just the basecoat and no clear on the interior and it looks like original and is very durable. A metallic base dries with a satin finish and a non metallic dries with a flat finish. That is with using PPG urethane basecoats
I think I will go with the interior the same as the outside. I have seen pictures were people paint the part that sticks out on the dash a different color than the rest. What do you guys think about this?
I've recently used that ready to spray dupli color paint that comes in quart cans. You can buy it in just about any auto parts store. I used the black. Its a laquer paint and dries with a semi gloss/ semi flat look thats real close to the original sheen. Its thin and will run if you're not careful and must be sprayed durring low humidity. Other than that, I was pleased with the results on the 65 Chevelle metal dash that I painted with it.
