I used System Three'sTrial Kit.  The resin came in an unmarked bottle with
the instructions wrapped around it.  These instructions said to use a 2:1
mix.

The instructions said the large bottle was 'Part A' and was to be mixed 2:1
with 'Part B'.  Once the instructions were removed from the bottle there was
nothing to indicate what the large bottle was.  There was no bottle labeled
'Part B'.  There was one labeled '#1 Fast' which, after careful analysis, I
deduced was the hardener.  The analysis?  Well everything else was carefully
labeled and I didn't think I wanted to mix powdered wood flour or
microballoon thingies.  The Silica Thickener gave me pause but I thought
mixing liquid and liquid was a better guess.

Everything else was clearly labeled and well worth the 10 bucks.  There's a
fair amount of everything.  I did 2 foot stern and bow strips using 3 layers
of fiberglass each plus fixed a crack in a hatch cover and used less than 25
per cent of the epoxy.  I used most of the fiberglass though.
