Great product. Easy to use. Covers nicely. It has been 6 months in the sun and so far is holding up well. Strong

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.

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.

Got the slow cure for a jon boat transom. It has worked well and cured hard without much effort. If put on thick it does take a while to fully cure talking 4-5 days. It’s hard to touch in about 1 day but it’s still soft if pressure it put to it or trying to sand some of the drips. I noticed no bubbles in what I was doing without me having to do anything but my work piece wasn’t very big.

Good product for the price

Good products for repairing my boat

First, I'll discuss mix ratio - advertised as 5:1. That's confusing, because the bottles say 2:1 -- Here's the answer: Each stroke of the plunger in the hardener bottle will dispense one "unit" of hardener. The plunger in the resin bottle is larger - it dispenses 2 1/2 times as much per stroke. So 2 strokes from the resin bottle is 5 units, while one stroke from the hardener is one unit -- result: 5:1. Now to the performance issues I have: First, the hardener bottle is for "FAST" hardening, although the description on the Amazon posting shows and says "SLOW" hardener. I prefer FAST, so no complaint - but it doesn't match the advertisement. I"m repairing the engine hatch on my boat, which has edge damage due to water intrusion into the plywood around the edges. I removed the old gelcoat and the rotted plywood, applied a coat of mixed "Total Boat" epoxy to both the original fiberglass edge of the hatch and to the surface of the replacement new 1/8" marine plywood, which i had rough sanded to get good adhesion. I clamped the plywood against the original fiberglass edge using multiple clamps (see attached photos), and waited. The next step would be to cover the plywood strips with fiberglass cloth, then sand, add a fairing compound, smooth, and gelcoat. I haven't gotten that far. After 4 days at 70 degrees, the epoxy was still tacky, so I heated the area with two space heaters, to accelerate the hardening. 30 minutes later, the resin started dripping out onto the table! Removed the heaters. Now it has been 5 days, and the epoxy has returned to the tacky stage. The overall repair of my hatch will require a lot more epoxy, since i will be replacing all of the original plywood in the rest of the hatch. That will require 4 layers of fiberglass cloth, so I bought two "Total Boat" epoxy kits -- neither of them returnable. I've used a very small amount of the first kit. I cannot afford to wait a week or more between coats (assuming this stuff ever hardens) - so it's going on the shelf and I'll order a name brand replacement kit.

Great product. Works as intended.
