epoxy melting foam?? what type of epoxy are you using??? IF ITS FINISHING RESIN MAYBE BUT NORMALLY NO. ALSO THERE IS A BETTER WAY TO ATTACH SHEETING TO THE FOAM-DOUBLE SIDED TAPE -AVAILIBLE FROM WING mfg WORKS GREAT & IS LOW WEIGHT. CONTACT CEMENT WORKS TOO BUT USE ONLY ENOUGH- DO NOT OVER DO. i DONT KNOW HOW MUCH THE OBICI WOOD WEIGHS BUT YOU WOULD LIKELY BE BETTER OFF USING BALSA.trim is availible from many sources. Solarfilm??? didnt know that stuffwas still around. never had good results with it-too soft.
