laminating epoxy that is in the 100:25 range, such as Al W wrote.

E-Z Poxy 100:45 by weight

MGS 285/287 (and 335) 100:45 by weight

Pro-Set 100:30 by weight

AEROPOXY is 100:27 by weight

ACSpruce's data on the West System 105/205 spec was "5:1"
which suggests it is a volume measurement, but it doesn't have
the Rutan Blessing, last I knew.

IIRC, Perry Mick used MGS 335 and runs auto fuel in his EZ.

That’s good news.

Just a reminder, all epoxy that is fuel exposed must be high ratio type.

Like 4 to 1. 50/50 ratio epoxies can NOT handle “fuel” over time.

That’s bad news. Should I conclude from this that EZ-poxy (44-56 by weight) will NOT handle fuel with ethanol? I assume when you say “fuel” you mean fuel with ethanol, since experience has shown that EZ-poxy has handled auto fuel for periods of 15 years in some EZs.
