Sprayed a seal coat (Actually 2 coats) of thinned epoxy primer as my seal coat. Prior to this, I had multiple coats of Featherfill G2, which turned out fine, but there were some low spots that needed some filler, which I did and I eventually block sanded 220, 320, 400, and then 600. There are some spots that are clearly visible through the primer.

I am planning on letting the body sit until next year when I am done with the drivetrain. I am going to block the primer with 600 or maybe even 800 prior to spraying the topcoat.
Should I put another coat of epoxy on, or will this disappear when I do my final blocking prior to color?

I would sand what you have and spot spray a full strength coat of epoxy. i'm amazed that it didn't cover with the sealer coats. maybe you put it on way to thin?

I just sprayed this last night and am well within the overcoat window. Would you still recommend sanding first?

If your in the recoat window just spray it, one day should work perfect.

The recoat worked great, but unfortunately a huge bug liked it too...

Whats the best way to handle this? Sand the bug mark, fill, block, spot spray?

Thanks

If you don't think it will sand out, repair and spot spray
