TotalBoatPolyester Laminating Resin - Marine Grade Fiberglass Resin and MEKP Catalyst for Layups and Repairs (Quart)

This stuff just works!I used it over a “less than stellar” raw fiberglass car body and it filled in minor defects and gave me a great surface finish after sanding and polishing.It is the most economical product I could find.Additionally, the color is a nice shade of black.

Things started off not so well with this order, it was missing the MEKP catalyst when it arrived. Since it was a hazmat item Amazon did not except returns and there was no way replace the missing product and made me order some separately. Not a huge thing as its cheap but was disappointing to say the least. The second thing was that it appeared to be leaking on arrival, I assumed it was from rough shipping but the seal was still intact so I figured one next to it during storage had leaked on it and it was just residual, again no big deal. Things came up and I wasn't able to get to the project that I had purchased this for so it went into storage in a climate controlled basement, unopened for almost a year. When I finally got around to opening it, I found that it was extremely thin (thinner than water), and had a very strong alcohol smell to it. It didn't seem right to me but I was unfamiliar with laminating resin as I have only worked with finishing resin. I tested a small batch and it hardened up slightly but didn't seem right, plus about 80% of its volume had evaporated. This stuff was not going to work for my needs so I was needing to order something else. I was pretty sure that this jug was bought before and used and then refilled with acetone and sealed up and returned. But with being unfamiliar with this type of resin I emailed TotalBoat directly to get verification that this was not how it was designed to be before I ordered more and ended up with more of the same thing that wouldn't work for my needs. They ended up sending me a new gallon at no charge after I told them about what was going on. I never asked for or expected a replacement, they just offered it, even with it being a year old purchase and had absolutely no proof that I wasn't the one who diluted it and ruined it myself, or just making it all up to begin with.Anyway, long story short. My original product turned out to be diluted by approximately 80%, TotalBoat sent a replacement at no charge and this stuff was exactly what I was expecting. Great product and even better customer service by TotalBoat.PS - Amazon was zero help and offered no support even with the missing product on day one.

Still a little expensive, but I've been critical of total boat before - this is some of the best quality fiberglass resin I've ever purchased. Performs exactly as expected, under less than ideal temperature conditions, has a smooth blue color that changes slightly when you add hardener and goes nearly clear when it cures. Excellent product. Highly recommended (since everybody had gotten wildly expensive on resin, a few more dollars than the "other guys" to get this high quality product is worth it.)

Not the easiest polyester resin to use. It was a guessing game to get the MEKP just right. Seriously wish they had better instructions. Looked at Boat works today and asked question but Andy would not give me advice unless I was a paid follower on Patron or what ever . I called the James Town Distributors, and left a call back number. They called me back with in a few minutes at which time they explained the Mystery of MEKP calculation. Once I got the feel for the product it was really easy to use. The lay ups went real easy. One really positive note here. James Town Distributors has shifted away from shipping this item in a metal can. It now come in a plastic bottle which is awesome from shipping. My package arrived damaged but the item was perfect. Total Boat seems to target the weekender DIYer. If you have questions just reach out to them. The staff is nice and informative and are willing to share what information have for free......... I gave 3 stars an ease of use because it is a little stressful at first, so be aware of this

This is the 2nd and 3rd gallon I have purchased. I noticed on the first 2 gallons as at this time I have not open the third gallon. When I wet out 1708 or CSM and come back the next day this stuff is not tacky at all. First 2 gallons did not stay tacky.Its still a good resin but I would not recommend and would be going back to using the resin I used previously on another build I did.**Updated its still tacky, just need to give it a acetone wipe and its tacky.

No complaints, did what it is supposed to do!

Very little experience working with fiberglass, a little nervous taking on glassing a wooden canoe paddle blade. Directions super easy, the mixing/curing color change was helpful, it applied (chip brush) and cured exactly as I wanted. When combined with the 4-oz. cloth from another vendor, the canoe paddle came out better than I hoped - it doesn't look like a "first attempt."

I love this resin. It’s easy to work with. Great price as well!
