A black canopy can easily reach the same temps in the sun. A large canopy may sag when softened, smaller ones may distort due to mounting stresses.<BR>

Anyway, a sure fix is to use the stock canopy as a plug. Simply glue the flange to a backer board, wax, apply PVA and lay up a fiberglass mold. Use the mold to fabricate a glass canopy. I use 2 layers of 3/4 oz, 3 layers 3 oz S-glass and a few CF "ribbons" vacuum bagged into the mold. (Bleeder cloth and absorbent backing in the bag to minimize resin.) West 205 laminating epoxy works well. The glass canopy weighs about one-fourth to one-third that of the plastic version and is much less heat sensitive. An easy way to reduce weight and not at all as hard as it may seem to do.<BR>
