13622Re: Marine of standard plywood
- Oct 3, 2006I happen to have a very functional ACX plywood boat covered in
polyester laminating resin and 6 oz glass living in my back yard... Now
the punch line.. The boat is over 20 years old now.
If you follow the rules, polyester is fine. You have to do a little
homework though. Laminating resin does not have any wax in it and
penetrates the wood well to adhere, and stays tacky even when cured to
accept the next layer. Most polyester resin purchased in the can from
the auto parts store or Wal mart, does have wax or other agents in it
that rise to the surface and protect from air during polymerization,
letting you have the smooth non tacky surface. If you try to bond a
layer of glass to this, you will indeed be disappointed.
So be careful when "experts" speak off the cuff. All that said, I like
epoxy resin better.. handling properties, odor, adhesion, and the fact
that it is more close to water proof.
