TotalBoat 5:1 Epoxy Kit (Quart, Fast Hardener)

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

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

I'm so pissed off with this product they should be boycotted and may I from the start say it's not Amazon's fault. I bought Total Boat Fast Hardener and Resin to be used with 3inch matt tape to repair the seam in the aluminum roof of our pop-up camper. Easy-peasy, so I thought. Did all the proper preparation, grinding the roof and cleaning so it will bond good. Read the instructions of both resin and hardener containers (with a magnifying glass, cheap buggers can't pay for bigger instruction lettering). "MIXING : Mix ratio 5:1 (FIVE parts RESIN to ONE Part HARDENER). Mix for 1-2 minutes, add fillers if needed." I had been waiting for the temp to be where all would be good to cure. I mixed 5 parts (pumps) resin to 1 part (pump) hardener. Once I had completed the job went to camper approx 90 minutes to check on cure ....... still sticky and far from any curing taking place. Rang Jamestown Distributers and talked to Bugalugs and he then told me I should have mixed 1 pump of hardener to 1 pump of resin. Told him that the instructions never said that. "Ahhhh" he said. Did you get it through AMAZON?" Yes, I did!!!! Well, if you had bought it through us direct, we would have included the proper mixing instructions using the Ratio pumps. That is how I mixed the resins using the Ratio pumps, I replied to the Big Egg. Jamestown are passing the buck. So, I have wasted a bunch of money and time and guess we aren't going camping. I will look elsewhere for a resin company who can supply good instruction. In the meantime, I won't buy Jamestown Distributors products, and if they think that Amazon isn't sending the correct instructions, why are they still selling on here? PS: Why doesn't Total Boat just put the 1 pump to 1 pump instructions right on the BOTTLE??? And make the print larger so that we all can read it???

95% of the poor reviews are because of user error. 1 pump of each not that hard. You are the reason they put do not drink on gas cans.
