One question,

What are you doing to the 1/16" balsa to keep it from absorbing to much resin? My experiance shows me that the balsa acts like a sponge.

I have heard of people using AquaNet hairspray in the purple bottle, they spray it on until it pools, then once dry, lightly sanding it, repeating this a couple of times.

I would love to hear so other ideas!
