Default Fiberglassing Between Two (2) Panes of Glass

Please help. I am glassing one of two plywood roof top panels for the 25% O-1 Bird Dog and I want to put it between two panels of glass. The glass panels would then have weights placed on top until the epoxy cured to ensure a straight, flat panel to be installed on the roof. Should I use a release agent (car wax) of some kind on both inside panels of the glass? I'm not going to tell you why I asked that question (smile). Also, about how long should I let the composite of wood/glass stay between the glass panels under the weights? Many thanks. Chic

Get some 2 mil Mylar, wax it and do your panel between two sheets of the waxed Mylar. Then put between the two sheets of glass. How long depends on the epoxy system you are using and the temp where it is curing.

Many thanks, one last question, once dry, how do I remove the wax that accumulated on the now glassed plywood prior to my sanding, priming, and painting it? Again thanks for the help and advice. Chic

You buff the wax off the mylar. There won't be much transfer to the laminate. Wipe with acetone, sand, wipe again and prime.
