2001 Logic Marine
By Logic Marine from Fort Lauderdale

I purchased this product under a recommendation from my boat mechanic, I need it to repair a quarter inch hole in the top of my plastic fuel tank. One of the easiest products I've ever used, literally a five minute job. I also repaired a 4 inch tear in my transom splash well. The entire boat is made of Roto molded polypropylene The stuff dries hard as a rock. My only complaint is strictly an aesthetic complaint. I wish the product dried white, and not an amber gold. I will recommend this to my friends.

Bottom Line Yes, I would recommend to a friend

Dagger Royalex repair
By River Pilot from Central Oregon

Verified Purchase

I will float the boat this weekend. And test it on the John Day River in a couple of weeks. Repair appears quite strong. A 24" crack caused by snow sliding off the garage roof and pining the canoe to a plastic crate. Ugly

Bottom Line Yes, I would recommend to a friend

Yes I would recommend this product.
By John from Louisiana

Verified Purchase

I have a old town royalex canoe which I had brought to Houston for rescue efforts after hurricane Harvey. During our first night there a car rammed it and bent it in have. Having large creases on the outside and cracks on inside it was either job weld or g flex. I faired the creases out and repaired cracks which were three about ten ten inches long each. Worked great sanded out well and repainted with krylon fusion for plastic.Like new now and feel confident in its structural integrity.

Bottom Line Yes, I would recommend to a friend
