Larry I did use some of the pink foam when constructing my canopy frame. While it is not a structural component such as a control surface, do you think this will be a problem? There are three to four layers of kr glass covering the foam to create a box beam like member that the canopy was then glued to with flox. Should I consider building a new frame or wait and watch to see if there will be an issue? Pete Klapp
