Link is not working .. Prolly by our host ...
Check to see if it is laminating resin with no wax ... For multiple layers that is what's best used ..

Well, if it says Boat Yard on it . . . :thumb:

It is a decent resin so you should have no worries. Be sure to mix it in small batches.

I wouldnt use it. The product page said it may or may not contain wax. I'd prefer no wax, or at least to know if it has wax or its no wax

Iboats sells resin, please dont post competitors, even if they are right down the street.

The product you linked specified NOT for below the waterline, never seen that exception before @ polyester resin ....

cmiller319, you can't post links for products that are sold on the iboat store. Yea I know.

Usually folks use a laminating type polyester resin (435 is the number on some laminating resins). And that is without surfacing wax. Otherwise you have to sand and/or clean the wax off the surface if you want to poly over some you already put on the hull. Before you get too involved, have you read a few boat projects on these forums so you understand what it takes to install those things? I strongly suggest you take the time to read a few before you proceed. It is tons easier to do it correct the first time, then to have to cut out errors from not knowing how things should be installed. JMHO

And why would you need "a couple of five gallon pails"????
You only want enough resin to wet out the cloth, not enough to float the cloth. The strength comes from the glass cloth, not from the resin. The resin is only the "glue". More resin doesn't make it stronger.

He probably will use that much resin if it's a full resto ... But I would still only get 5 gals to start ... Sometimes these restorations get put on hold so you don't want the resin just to sit around ...Fresh is the best ...:)

I would suggest using epoxy resin, this way no worry with wax (there is none) an it will bond and hold to most anything. Draw back is it cost more

Boatyard DOES make Un-Waxed Polyester resin. When you go to the store make sure and specifically ask for it. It would be suitable for your build. I agree that 5 gallons is a good start. You will also need 10 yds of 1708 biaxial Fabric/Cloth. I think you'll find this informative.

Product description doesnt specify its available w or w out wax. Lists it as may or may not. Sounds more like you get what you get........

Boatyard Polyester Resin 5 GL; Non-spec resin. Contains a mix of different types of resins: ortho-, iso- & low profile. May or may not contain wax. Do not use below the waterline.

I had to do a bit of Googling since I did not see the original link posted. . . Looks like there are 2 brands of resin that go buy the "Boat Yard" branding. There is Evercoat ("Boat Yard") and FiberGlass Coatings, Inc. ("Boatyard") . . . so my bad for confusing the 2 brands. I've actually used the Evercoat brand.

As JB states, The Fiberglass Coatings, Inc. (Boatyard) would not be a good choice, if they are not recommending it for below the water line. Not sure what the resin lacks vs. other resins that makes them not recommend for below water line, but with that, there are better choices.
