Epoxy or Poly resin?

Mike,
You've got the opinions of two professionals, I'll add the opinion of an amateur that's done a little research and played with both resins.

Poly is "good enough", epoxy is better. Why? For an amateur, epoxy is easier to mix, easier to work with, and has little to no odor. A guy using poly resin in an attached garage may run the whole family out of the house with styrene fumes.

Epoxy also has better secondary bond strength, is water proof while poly is only water resistant, and has the best physical characteristics of any of the laminating resins. But it's the most expensive, too.

Either will work, epoxy will work better, last longer, and cost more. So, ya pays yer money and takes yer choice.

It is a lot cheaper then epoxy. but It is more then polyester. It is water proof. Some claim more water proof then epoxy. It has better secondary bonding then polyester resin. It is thinner and wets out most glass better and easier then epoxy.

Well i had already ordered the epoxy from Merton's in Massachusetts so i might as well use it, the guy there talked me into it. I will post some more pics as i make headway, just have to get through this nasty storm coming our way tonight.

Mike, I agree with the choice of epoxy because of it's superior bond strength and waterproof properties as others have mentioned. However, even though it doesn't smell, it's a LOT more toxic than poly or vinylester! There are some nasty chemicals in the hardener, so you need to take some precautions when using it! Check out this note I posted a few years ago. http://www.classicseacraft.com/commu...cautions+epoxy Denny

I used vinyl ester resin, it's not porous like poly.
