I don't have a clue which epoxy I used. I ended using 3 different types
over the 6 year building process. Two became obsolete. 2 gallon header was just above the main landing gear.
Lots of evidence there is no significance to speculations about ethanol
risk in tanks. FWIW.

Al,
What epoxy did you use, just for another data point? I'm using MGS 335 but I suspect, as you said, that high ratio type epoxys will all test the same. Thanks.
