Hughes Glue, aka FPL16A is Shell EPON epoxy with 2.5% thinner and a filler of Titanium Dioxide. It is better than T-88 ( in my opinion) but messy due to the coloration. I use T88, but would use either, depending on stock on hand. Zero concern regarding cold temps.
Developed by the Forest Products Laboratory, an agency of the state of Wisconsin. Orma said; Hi Tim I would be more concerned about the wood in the damp, and ice forming in the cracks and crevices. Good epoxy is not going to break. I can't speak about Hughs glue. Orma aka AviationMech 19 Years flying the KR-2 Ron Freiberger mailto: r.freiberger at earthlink.net r dot freiberger.... get it?
