TotalBoat Traditional 5:1 Marine Epoxy Resin

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.

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!

I like the pumps that eke the right amount of product, so they remove any guessing. I used the Total Boat resin in conjunction with fiberglass matting to make repairs in my sailboat. Make sure the surface you want to work on is clean and free of dust and contaminants and I wiped the surface with alcohol and tacky cloth before applying the resin and fiberglass cloth. There are numerous YouTube videos available. The result was great and solid and I am very pleased with the product and the fact that it was cheaper than the West Marine 105 and just as good. Just follow the directions and you’ll be happy with results

Set up and use are a breeze. The epoxy is a great product. The only disappointment so far is how flimsy the large bottle is. Trying to get one press of the pump results in the bottle collapsing because the plastic is so thin. Considering the TotalBoat name and the cost of this kit, you'd think it'd be a bit higher quality container. Especially since it'll take a lot of pumps to go through it. I'm not confident the bottle will last without some sort of reinforcement. Edit: Mine was missing the mixing sticks also. Just saying, don't picture it and mention it if you're not going to put it in the box.

I didn't think.they wor gona work good the are perfect for little welding jobs

NOT A 5:1!!! Forget the pumps. 5ml + 1ml is a 5:1 mixture. The cups have markings. We all got ripped off on the amount of hardener provided. If you follow the sites recalibrated instructions of 1 pump from each container, it's actually closer to a 2:1 or 3:1 mixture. Thus, shorted on hardener. Absolute garbage product. Been waiting 2 weeks for the mat glass cloth on a pair of doors to properly cure. Just peeled a section off as a rubbery plyable glass cloth sheet, after 2wks. At this point, I've wasted 2wks, wasted a fortune in cedar, wasted the time to shape the cedar into doors, and now I have to start over because I chose to trust Total Boat brand. After 2 or 3 weeks, you can attempt to sand, but it's gummy in unevenly cured areas. If you've recently purchased this product, return immediately! If you're past the return window, safely dispose. Don't play around with 5:1, 3:1, 2:1 mixtures as I did. None of them will properly cure. Now, purchase West System for 25% more cost. It will save you weeks or months in rework. The product failed to perform to reasonable expectations.

Best epoxy for carbon fiber. We are asking seriously stong structural material with this.
