Epoxy Putty Stick 113 g - Easy, Fast, Permanent Repairs Even Underwater - Repair Boat Hulls, Decks, Pools, Spas, Hot Tubs, Leaking Gaskets, Tanks, Gutters & More

Used to repair some holes in my fiberglass boat, this works very well. Be sure to keep your hands wet to avoid it sticking while you kneed it, but this filled the holes and stuck very well. Even needed to drill into it and then install a screw … it held just fine. Super strong and so convenient. I love this stuff!

This thing is amazing! It's super easy to use, super fast, and it holds up! I used this to repair chips in a ceramic bathtub and I couldn't believe how well it worked. My mom now keeps a stick in her fiberglass kayak for emergency repairs. If it's calm, you could literally patch something small without taking the boat out of the water!

After several failed attempts using JB Weld I decided to give this stuff a try. And it worked! It's worked every time I've used it. Would I recommend this to a friend...... definitely. This stuff is great... it's quick to cure and easy to use

Good to seal holes done at the wrong place, white finish; perfect for my travel trailer construction project.

Most pool companies use this product. What else is there to say.
