First, you need to remember to change the subject when you are changing the subject. Your question had nothing to do with "Wingspan". I almost deleted it because I have read enough about wingspan.
The ratio for mixing AeroPoxy is 1 resin to .27 hardener. For sealing the foam with the Micro mixture, put in enough Micro to have it pour about like honey. If you get it too thick, it will start rolling up the foam if you get that, just put in a little more epoxy and keep on going. ============= Hi,i have a gal. Of aeropoxy& a quart of hardner&two pounds of micro ballons, I have to finish my wings, what is the ratial for mixing them?
