I like peel ply. I know it works. If the micro does not wet out, then it will just flake off and you will not have accomplished anything. A quick test on a small piece should tell the tale. Not sure about the "lighter" either as peel ply actually sucks up excess resin, but I will bet we are talking grams here.

Daniel R. Heath - Lexington, SC -----Original Message----- pour dry micro balloons over the wing and brush it around to fill in the weave. After drying just rake the excess back into the can. He said that this would be lighter than the peelplying method but how much weight are we talking here ? Is there a best way to do this ? Mike Sylvester
