I love this product. It was very easy to use. Before and after pics enclosed. Good to heat the room to 90 degrees if possible so you can pour several layers in one day rather than one a day because of the setting time is less in 90 degree heat. Sanding with 60 grit sand paper was as fast as sanding wood. Get this product. and wear a respirator. ... show more

    • you need fiberglass cloth as well
Size: Quart
I can see using this for a lot of projects. You do need to follow the instructions exactly to ensure the resin is the right mixture. It goes on easily enough and sands down after dry.

    • Worked for patching a kevlar canoe
Size: Quart
We got this too late in the year to do the full repair, but I took advantage of some 50+ degree days to do a test recover on a big scrape and it filled the scrape and virtually made it disappear. It was great to work with and cured to be very clear. Ultimately in the spring we will be reinforcing the bow which had ground away on landings to the point that it is leaking. We have the fiberglass cloth to rebuild the bulk and after this quick cosmetic patch, it looks like this is the perfect resin. Brought the back side of our canoe to near mint. Easy to work with, only problem is waiting for warm weather in Minnesota. Recommned! Price is decent, amount is perfect for our job. ... show more

    • Excellent for fiberglass recoating, too!
Size: Quart
I got this to recoat a fiberglass ladder that had exposed fibers due to UV exposure. Since I'm not using the ladder day in and day out, I don't mind trying to repair the fiberglass to get more years out of it. Once I got it mixed, it was super easy to apply and use, just make sure you take the prep seriously (though I didn't get it right in all spots, and it still worked excellent anyway). The hardening solution was a touch difficult to open and measure, but "close enough" actually worked out pretty well for me. Just be smart about what you'er mixing this in (the container) and what you're using to apply it, as they'll be pretty much ruined once you're done. ... show more
