Sanded through 2K regular build to epoxy primer

2

20mercury

I know I saw the answer to this but looked and looked and can not find it.

I have a 72 Corvette, razor blade stripped to bare glass, 3 coats of epoxy primer, then 2 coats of 2K regular primer, guide coat and sanding flat with 220grit, accidently sanded through the 2K to the epoxy primer, can I put on another coat of 2K or do I need to touch up the sand through's with epoxy primer first??

Thanks!
 
"400-600 wet depending on color."

Going back with Bryar Blue original trim tag color, kinda of a teal greenish blue, bc/cc, why 400 or 600 depending on color?
Which colors do better with 400 or 600?
 
Sometimes metallic can settle into coarser sand scratches and show the scratch pattern, solid colors don't have this problem. So 600 for metallic, which is what I am pretty sure your color is.
 
You are correct Bryar Blue is a metallic. So 600 it is.

Much thanks for the great explanation!
