Just another data point for you to add to your list.  Jeffco 1307 resin with 3102 or 3156 hardener is a 100:25 system by volume, or 100:22 by weight.  The differences in the hardeners are time to cure... the 3102 is a fast cure, with a 15 minute pot life, the 3156 is a slower cure, with 30 minute pot life.  I also use their 3179 hardener down here in FL where the temps get outrageous in the summertime, for a 45-50 minute pot life.  The 3179 also has a much lower viscosity than the other hardeners so it makes a thinner mixture... makes wetting out much easier, even with temps down into the 60s.  Once again, this is the resin system used in the Lancairs.

a 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.
