Interesting thread,

Epoxy will soften with heat, I use a hot-knife (old pencile type soldering iron with xacto blade) to rempme hinges and such. Also low heat gun for other areas like firewalls. Epoxy is used to seal the normal lawnmower metal tanks, using my converted iron I can simply take the cured epoxy out.

The main differance in marine use is formula, and impregnating gass. You can get it hot enough to warp or mold, but You can burn it around the edges of a hull fracture and have glass strands left behind. And the patching is blended with the original form.

Builbing plugs and molds with epoxy and polyester bases has many variables not seen in the boat industry, as a normal rule.

Mixers, pumps and chopper guns call for differant formulations, The 5 min or 30 min type does not require.

Ex Sarasota bay and miss it"
