Interesting idea. Lighter than glassing, Posted by: g2d on Dec-27-12 8:14 PM (EST)
although the 2 layer S-glass patch under my solo pedestal has lasted better than G-flex and aluminum powder could do.
An alternative might be G-flex mixed with graphite powder. Many plastics made UV resistant use graphite or another black additive. As graphite is scraped loose, it may lube a bit.
