Hi

There are a lot of good suggestions here.

Note that this concept takes practice!!!!

Here is what has worked for us and minimizes sanding. We use this method to make our plugs. I hate sssanding.

West system epoxy thinned with alcohol to a hot syrup like viscosity. Why thin?? To ease the bond to the wood, using less resin, avoiding the .75oz cloth from floating above the resin due to thick viscosity. .................... But you can squeegee the extra thick resin off with a credit card!! Sure one can but, the thin resin takes a minor squeegee. Then once cured, you can light sand and begin to use primer. We use duplicolor Hi fill primmer/filler from pep boys. lacquer based super fast drying.

West systems sands fast and powders up when cured and does not clog the sand paper.

Try to get .75oz glass that is not folded. Folds have creases that may not want to lay flat.

(We actually use a second coat of thick resin once the first thin layer is cured. then squeegee and sand smooth. Fills weave way faster then primer. We do this because our models are to become plugs for composite parts and not flying models. although they will work for flying models as well.)

Again, practice


Also the thin resin penetrates deeper into the wood and adds more stiffness to the balsa.
