As long as you stay with the one brand and type of paint you will be OK as far as bleeding and compatibility goes

I would try to fill most of the weave with clear.

The dope is pretty food about the brush marks leveling out as it dries

I feel that a small spray gun would be more viable than a air brush. Use the air brush for trim

I liked to sand between coats after about three coats with a rubbing compound job in the end. It will look like Monokote.

Try to not put on any more paint than you have to because of weight
