Get the surface you are applying to wet enough to allow some squeeze out of resin after the lay-up is applied.

Use a bright light at an angle to find the bubbles. Before the outer plastic is peeled off, check again, careful not to pull the wet glass and get more bubbles. All this takes practice, patience and slow hardener with the warm temps of summer. Satin glass cloth (supplied with your kit) is the most difficult, the optional carbon cloth or basket weave glass does not hold bubbles but is heavier, just thought I would throw that in.
