Great fiberglass
Put a hole in my boat so I started by fixing it using spray foam, one layer of fiberglass and resin, then I use two layers of polyester structural filler to make the surface level. I put three more layers on of fiberglass and resin, and then gel coat and it worked great. Not the prettiest but no water got in the boat.

(POWDER COATED) Chopped strand matting that u can't get anywhere but here, !Epoxy users rejoice!
After my first order and application of this product I immediately ordered 5 more!!! This stuff is fenominal for glass work with epoxy and the only product that is available with powder coating! Yes it is messy and you will get strands everywhere but if you just score or tare it slowly it holds together fine. Also I have to say if you need to get 90% or just tuck it under it will comply! Just keep dab dab dabbing until the epoxy kicks and you will be just as satisfied as I am!

Worth every penny
Put a new wood floor on my boat floor, and this stuff with opoxy worked great, super strong and easy to tear, once cured, it feels super solid, and the amount that is comes with was perfect

Worked well.
Worked well for my project. Yeah it's folded, but worked out well and weren't a problem.

Good quality and price. Fast delivery
It lays down good. I’m a beginner at making a motorcycle seat pan. Once it setups, trim before it’s 100% hard.
