West Systems 105 resin and 205 hardner is what we all need to use this time
of the year. It is fast curing...2 hr @ 90 degrees, 4 hrs. @75 degrees, 8
hrs @55 degrees.... which is about four times as fast as EZ poxy. Summer
pot life 5 to 10 minutes. "Spruce" or your local marine store has it. Buy
and Gal resin and Qt hardner with the plunger pump kit that will give you the
5 to 1 ratio.
It has very similar ultimate strength and deflection rigidity and EZ Poxy but
much better laminar strength especially secondary layups like assembly.
Combined with 410 microlite filler it is the BEST for fill and sand.
