TotalBoat 5:1 Epoxy Resin Kit (Gallon, Fast Hardener), Marine Grade Epoxy for Fiberglass and Wood Boat Building and Repair

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!

TOTAL BOAT IS BEST

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.
