TotalBoat 5:1 Marine Epoxy Resin Kit for Bonding, Filleting, Coating, and Laminating - Use for Fiberglass, Wood, Carbon Fiber, Boat Building, Repairs, Woodworking (Quart, Slow Hardener, Pumps)

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.

Great product. Learned about epoxy based resin and polyester resin on Youtube. Glad I found that info and I purchased Total Boat Epoxy to repair two snowmobiles. Both hoods one a simple crack and the other pretty much a big mess with multiple cracks and problems including a body with a torn out front hinge. On that I glassed in a couple layers of woven glass on the inside of a messy fiberglass tear after trimming it up a little. It's a vintage 70's sled with a fiberglass body. Duct tape was used as a soft form on the outside and it looks just great. Nearly zero transition between the epoxy and existing gelcoat. The repair feels as strong as the original if not slightly stiffer than the other side. I have yet to run it and see if the repair will hold. My prep work was very careful. Degreasing and lightly air sanding with a 2 inch 3M disc to expose fresh material to adhere to. Masking tape makes great dams and protects surrounding hardware I found. I am confident these repairs will last and I don't think I could say that if I were using a polyester based resin. I did pop the left over cured resin out of the mix cup and tried to break it. I could on the thinner cured part, but it was clear it was a pretty strong material. I ordered the fast cure and in a heated shop at 70 degrees it took a long time to cure I thought. Just about two hours. And I am reading that that is normal at that temp. I am however very used to automotive products cure times which is much quicker as in minutes. No hurry with this stuff unless it's very warm out. Wear your PPE as this stuff has a strong odor till it cures. And it sticks to everything. Gloves and disposable brushes are a must. Overall the product was great to work with. I see many other applications for this product. I have only used fiberglass products a couple times before. So an amateur I am. Good stuff. Great strength. Easy to work with. I measured and did not use the dispensers. So I cannot comment on those. 5 stars

I had to replace / rebuild some rotten deck and part of a stringer on my '93 Maxum 1800. After much product research, I decided to try the TotalBoat Epoxy 5:1 kit with the fast hardener. I have used almost three gallons via three different orders.I have had no issues and great results with each. When I started, I used a scale to ensure the pumps were measuring the correct amount - they were within a gram or two every pump of both parts, thus ensuring proper mixture. I am comfortable enough with the pumps' calibration that I no longer use a scale and every batch sets up fine. Working in the heat, I would only use five or six pumps of each, work it, then start another batch. That ensured it did not set up before I could get it where I needed it. With cooler temperatures, I had more time. Adding fillers for fillets is no problem. I like that it comes with the calibrated pumps, two mixing bowls, stir sticks and gloves, though the gloves are pretty thin. Everything you need is in the box on arrival. Since it is an epoxy resin, it does not stink like the polyester resins common at local big-box hardware stores. Though the product is not necessarily cheap, it is much less expensive than some of the more popular brands on the market, and those do not include all the extras. This is a quality product and good value. The shipping was very fast. I'm 100% satisfied with both the product and the seller.

WORKS JUST LIKE WEST AT LOWER COST

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.

First off, do not, I repeat do not use the mixing cups that come with this set more than once. I used each cup 3 times. And on the third use, the resin melted the cups, and even got so hot it was smoking. Had to throw it in a puddle and pour more water over. It had the water boiling. Now, going backa couple of weeks......I used this for the first time last night. I'm very impressed so far. A lot easier than trying to use the bondo brand and guess the amount of hardener. Word of warning. Once mixed, you have maybe 10 minutes before it starts to jell. And if you're wearing latex gloves, you'll be able to tell because it gets hot. And I mean hot. Also, the thinner you spread it, the faster it sets. Had some pool up on the boat bottom and an hour later it was still tacky. Highly recommend!

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.
