Great to work with

Did a great job soaking into the mat cloth that I was using. Spread very easily. Misjudged the amount that I needed and ran short by a gallon on a 4 x 6 patch on the boat deck using two layers of mat cloth. Had to run out and grab some JB weld. JB Weld was thicker and did not saturate the mat as easily, It was like night and day.

Resin and gel coat

1st time replacing boat floor. Should have bought the 5 gallon pail, instead I had to make 3 different orders. They showed up the same week everything. Awesome!
Was so nervous after reading about the horror stories of not mixing properly. Too cold, too hot. But every pour and lamination worked perfectly, even the gel coat! Which made everything look professional.
I'm grateful and indebted to truecomposits
sevice and product. Now I'm on to filling and coating all the screw holes with confidence. Thanks again.

Marine Polyester Resin

This is the second 5 gallon bucket I have purchased and very happy thus far. I will say I prefer the plastic bucket over the metal pail though. No issues with the resin. I am in South Florida and temperatures have been in the low to mid 90’s so I can only mix 8-12 ounces of resin at 1% at a time or else it starts to jell up but that’s a heat issue. I am doing a complete rebuild of a 1969 Aquasport so I will be purchasing more of this resin to finish I’m sure
