Hey Peckinpah, I’ve lived about 3 blocks from Allen for 30 years. Looking at your post, you most likely didn’t thin enough, ( orange peel ),
and applied too much paint ( runs ). It really is a juggling act to find the balance, but you’re probably not that far off. When you wet sand, if
you dry an area you’ve just finished, you should see a very consistent flat ( not shiny ) surface. Anything in the way of dimples or craters needs
to be sanded some more. In the early coats, you are adding color and filling in small imperfections. Take your time painting each panel, and as
you finish each new patch, go back and check your previous one for runs. There’s time to still work runs out with the roller ( or
foam brush ) so you don’t have to sand them later. By the time you get to your last 2 coats, you’ll have a perfectly flat surface to buff and wax.
If you were to do all your painting and then come back and wet sand, you’d have to sand right through several coats of paint to get it flat,
and you would be able to see where you burned through.
