Polymer World- 1 Gal Polyester Resin with Rolled .75x50x5 Yard Chopped Strand Mat, Fiberglass Kit for Boats, Cars, Surfboard, RV, Canoes, Jetski, Watercraft, with MEKP

I used this to fiberglass in new stringers on a old Bass boat rebuild project. Good product and very happy with the results.

Quality products durability ceep

Good working time, perfect amount to replace floor section in boat after tank replacement. Pretty affordable compared to local shops.

Used it to reinforce a weak floorboard section in a 50 year old car. There were a few pinholes showing through, but floor was basically sound. So I sanded the interior side of the floorboard down, and applied 3 separate layers of resin and fiberglass mat, to seal, strengthen, and protect the floor. I used a stiff, cheap disposable "chip brush" to brush the resin into the fiberglass mat, and press the mat down. Just lay the mat down on the surface first, and brush the resin through the mat. Resin and hardener work fine, unless it is a really cold day... Then, you must use a heat gun, or space heater to get the temperature up to normal room temperature, so that it will harden. Because the kit I ordered uses the random strands of glass (fiberglass mat) it is much stronger than the fiberglass cloth. The amount of hardener included, was plenty enough to harden the gallon of resin. Just use the amount of hardener recommended, don't try to over catalyze the resin by using too much hardener. I used a disposable plastic measuring cup, to measure out each resin pour. Be sure to have good ventilation, and a pair of disposable gloves are a great idea.

Why did you pick this product vs others?:Very good price point. The only issue was the amount or hardner. I had to buy two more tubes. It only came with one small one. It was not enough for the entire gallon.

Product had a good long working time. It is a little runner that I expected but once fiberglass is saturated, it holds in place. Smell of product is very strong. Glad I bought a new respirator. The amount of hardener given seems a little short and will have to buy extra. Maybe it is the perfect amount if you mix the whole gallon at once but I will be doing around 10 mixes for my subwoofer enclosure. I like the fiberglass included because it doesn't make your skin itch.

Worked great for building my subwoofer enclosure with tons of material and at half the price or less than local stores

Highly recommend
