Keep blocking, paint, or reprime? Here's my VFN fiberglass hood that's going on my 94Z.
I shot it with Southern Polyurethane's Hi Build Primer (after poking all over the hood with a pick, finding a few weak spots that broke through, and filling them). I also fitted it to the car before shooting.
So I've been block sanding. I started with 180 grit, and just finished with 320 grit. My question is - should I paint now, block with 500, or reshoot a layer of primer to add some thickness above the break-throughs? I'm using 3M's Guide Coat (the black powder).
The break-throughs are pretty much symmetrical, which leads me to believe they're high spots that are molded in with the building process of the hood.

not only for the matter of blockin it out, but on that u will want to paint over a complete fresh coat of sanded primer because, your basecoat will sink into the fiberglas and gelcoat and blemish out, and 600 would be a goood choice for wetsanding your new primer out
