Used 5:1 Total Boat to replace Transom in a 14' Monark, 1974, that I am restoring. Purchased the Gallon size kits several times, works well. Easy to use and easy to shape and sand. My only wish, is that the Hardener was larger in size. I use that 5:1 ratio and always run out of Hardener before the Resin... Approximately 2 quarts of Resin left....

Mixed, using the 5:1 System, works Great. My only trouble, I end up with a least a + Quart of Resin. Wish you Hardener size would be 36 ozs. I usually mix using the measured containers with the 5:1 system equaling 8 ozs. and, as stated, end up with + Quart of Resin left.

I just built a Michelak Larsboat tandem kayak using this epoxy system. I needed some more epoxy and was going to get some MAS epoxy as I had used it before. While In the store I saw the total boat and decided to try it as the price was much better. The guy at the counter said fast hardener might be too fast for me, I found slow to take forever. I had to keep scraping the runs off for what seemed like e half hour after each seam was wet out. If you live where it hits 100 degrees for more than a few hours a year, or work in the hot sun, slow might work for you. If you build in a nice cool new england basement, get the fast hardener. For those runs that you hate, and redoing fiberglass epoxy or paint on a wooden boat, get the Wagner paint eater, I've used it to redo runny seams and repaint boats. It takes epoxy, paint and fiberglass off, but won't touch the wood unless you hold it there for long after the paint is gone. I could still read my pencil marks just like the hull had never been painted.
