: Like Shawn said, you probably mean polyester resin.

: Polyester will work. It is not as good as epoxy for bonding and
: waterproofing, but it will work. If you are really strapped for $$$ and
: can't build a boat unless you use the cheapest stuff available, go ahead
: with polyester.

It looks like some of that US Composites epoxy can be had for $25 a gallon--this is cheap for epoxy, and probably not more expensive than polyester. Wal-Mart has polyester resin for $26 a gallon.

: I know of several polyester strippers that are still going strong after 10+
: years. They don't look that great, but they still work.

I kicked around the idea of building a one-off glass kayak. I was thinking of polyester, but for as cheap as I can find epoxy now, I'm not as tempted to try the polyester for a whole boat.
