Superb wood filler
Rather than replacing more than a dozen rotted deck boards. I decided to try to fill the "ravines." I tried many wood putties: n'yet . Bondo? n'yet (Became unworkable too fast for my application). This kit with its slow hardening was perfect. Beyond being simple to use, with the two attached pumps pre-measuring the correct amounts of the resin and hardener. I decided to WILDLY experiment with "additives." First, I added a couple of scoops of Durham's Water Bingo! Mixed easily and perfectly increased the amount of the glop and was easy to spread into the ravines. Dried hard as a rock but it must be abraded hard for painting. Next, I stuffed steel wool into craters, which are deeper than ravines. Then I infused the steel wool with the mixed epoxy. Why? Epoxy bonds with steel and throws off heat to boot. The gaps I filled with steel wool and epoxy are clearly stronger than the original wood fibers because solid steel....Btw: you can perform microsurgery on the "treated" steel wool if you have a competent grinder with attachments. Finally, I mixed grout with sand into the epoxy. Why? Because the sand in this concoction, when used to fill shallower gaps, provided a surface onto which coating would better adhere. Success. Moral of the story: I would have been far, far better off, prying up the deck boards, purchasing new ones, and installing them. Why didn't I do it? I am a retired desk jockey and when I started the project more than a year ago, I did not have the carpentry skills to cut and replace the boards. I have them now. Absolutely no regrets even though the filled-in boards are less than cosmetically perfect. Two warnings: you should absolutely not experiments with epoxy additives. Use only those that the manufacturer prescribes. My outcomes were fine but yours may be disastrous. Second, I could care less about bubbles in the epoxy. Accordingly, my recommendations are expressly limited to the use to which I put the product.

Easy to work with when you follow the mixing instructions
I am building a wooden boat and I chose to use the TotalBoat Epoxy Resin Kit (Gallon size, Slow Hardener) to fiberglass the wooden hull. This is a 5 part epoxy to 1 part hardener. The kit includes pumps for the epoxy and the hardener along with some disposable gloves and two mixing/graduated plastic cups. The cups have markings for several mixing ratios. I used the 5 to 1. Fill the cup up to the level you think you need and add the hardener up to the hardener line. Stir for at least one minute to 2 minutes and go to work. When it is properly mixed it will look clear as water. I have been pleased with the working time of the epoxy. If you are working in direct sun and/or hot weather, you may find that it starts to set/harden quicker. I am working outside in the shade and I have plenty of time to apply epoxy, fiberglass and more epoxy over the fiberglass before it even begins to harden...hardens overnight.

This is the 3rd time ordering this product through amazon. 2/3 times that I've ordered it, UPS has absolutely destroyed the container and I end up receiving a re-boxed package that's missing half the contents and the other half is damaged spilling epoxy all over the place. Do NOT order this through amazon. Go straight to Total Boat. Aside from that, this epoxy is 10/10 and I'll continue to buy it from Total boat.
