Magic Wand for air bubbles found at

Given your scenario, sounds like the bubbles were due to something other than an application SNAFU. I would recommend one of these notched rollers (I use them in every layup I do to eliminate air bubbles) but check the project periodically during the cure. If you catch these kind of bubbles in the gel phase, you should still be able to work them out with very little chance of them returning.
Besides the air pockets, that's a gorgeous layup.
