fiberglass notes

I have not tried to thin WEST with IPA. I have thinned regular epoxy
with IPA and it seemed to work OK. The only place I can think of
thinning the WEST is painting the interior of the hull for water

Working with WEST is similar to polyester resin, but it is stronger,
doesn't smell bad, and hardeners can be selected for your
application. For example if I was mixing the epoxy for glassing a
hull that would eventially be painted I would select the extra-slow
hardener 209 which has a pot life of 45 minutes. That's much longer
than a polyester resin pot life. The down side is the cost, it's
pretty pricy stuff. Another trick is to mix in the graphite powder
and it gives the finish a carbon fiber look. Take a look at this
flash movie of a woodie US1M with graphite look deck. Thanks go to
Bill Jennings on the US1M site.
