the bubbles are not air, they are trapped solvents. if you force dry a
thick 
coat of enamel/polyurethane, the surface dries first and doesn't let the
stuff 
underneath out.  If you want to force dry, use many VERY THIN coats. 
Else, be 
patient.  Get dupont book on automotive painting if you want the long
story, 
or believe me if you want just the short story.

I have wound all three of my secondaries on a lathe and had good
results.
 The last two, I layered on thick coats of cleary poly and left the
lathe
turning while it dried.  I tried heat lamps and they caused air bubbles
to
come up to the surface and it looked like hell - but maybe the air
needed to
get out anyway??
