Waterproofing canopy?

[scarpenter]

Is there a product I can buy at say Home Depot or Lowes that I can use to waterproof the inside of my canopy? It will be approx. 3" from open water. So, I am conserned with being marine safe.

Okay so no one wants to reply to my post. So here I go again.

What if I primed the whole canopy inside and out with Kilz oil based sealer, then painted with my black exterior latex paint on the outside, then put 2 or 3 coats of spar-urethane on the inside. then installed a small fan, and put a vent in the lid above the lights? That should be enough to prevent warp on pine canopy. Don't you think?

I built a pine hood for my 125, 6 ft. long. I painted the inside with kilz, the 2 coats of gloss white exterior latex enamel. The outside has 5 light coats of polyurethane, lightly sanded between coats. It has been in service for over a year with no warping. Much of the stability depends on how well the wood was dried before being used.

I always use a two part marine epoxy and have never had a problem. This stuff is permanent and completely waterproof. Dilute it with some acetone to get it to the right viscosity, and apply it like a varnish.

Something like this:http://cgi.ebay.com/ebaymotors/Epoxy-Resin-Boat-Building-MARINE-GRADE-High-Impact-32oz_W0QQcmdZViewItemQQcategoryZ50443QQihZ017QQitemZ270019735322QQrdZ1QQsspagenameZWDVW

Use tar. <_< >_> <_<

not sure if I'm kidding or not. Its been used for hundreds, if not thousands of years for sealing wood from saltwater.

I wonder if it would leach though, if fully dried out, maybe even sealed on top of that.

Give it enough coats of polyurethane, & don't worry..
Stay away from long unsupported pieces of wood. For example: If your tank has a center brace, so should your canopy.

We're putting on 2 layers of latex-based paint on the inside of my canopy, but the whole back and top of the stand is open so humidity isn't an issue.

3 coats of spar urathane will give you a nice thick water-proof covering.

I used 2 part epoxy then a water proof membrane for the sub floor you might get it from home depot or a marine store
