Paint - Repairing Base Coat

mokid said

Took the hood off my 69 Dart to paint it. Hung it vertically so I'd be able to paint both sides. Had two problems:
1) Got a couple of runs (on outer side, of course). Tried to repair it by scraping runs with razor blade and painting over it. It looks marginal. Should I just wait, sand, and repaint? How long should I wait before sanding?
2) Found a bullseye (sunken place) on top side that I just flat missed when block sanding. Tried building it up with paint (like with primer). Can this be done, or am I stuck with filling, sanding, etc., the traditional way?

If I build up the "bullseye" with paint, how long should I wait before sanding it each time?

If I decide to lay the hood flat and apply base/clear one side at a time, how long should I wait before turning it over to paint the other side?

Ok, in my opinion:

1. I would block the run with 600 wet or dry sandpaper and water then hand sand it with 1200 wet or dry sandpaper and water to knock down the scratches especially if it's a metallic. If you don't break through to the undercoat you should be able to go right back to paint.

2. To correctly repair the bullseye, you should fill with primer if it isn't too deep letting each coat dry before putting on the next (this will take some time with air dry)

If you want to paint one side at a time, you should probably wait a couple of days to be sure you won't mar the surface of the paint when you flip it over. Setting it out in the sun to dry would help.
