A day at the lake!
I cut the bottom out of my boat and added a screen door. Used 10 cans of this amazing stuff to coat it. Out on the lake we went...I mean my boat is setting at the bottom of the lake and I lost my first mate, but still a day at the lake!

Easy quick fix
I used it to seal a couple small cracks in a canoe. So far no leaks! Works as advertised

Good stuff but be cautious!
PLEASE read to directions carefully because this stuff is full of dangerous and flammable chemicals. It does work for sealing leak causing cracks. Don't know how well it will last in sunlight but for a short term fix it seems to work fine.

Get creative
I use this on my shovel handle and outdoor work tools. It prevents splinters from those older dried out handles. It seeps into the cracks and groves providing a safer non slip grip.

Colorblind?
Ordered black. Received a can with a clear lid but the sticker said blank. Sure enough it’s clear. Not what I wanted but it says it’s paintable so I can make it whatever color I want. Would be nice to receive the color I ordered.

Great product
I have a fiberglass camper shell on my Ram and haven't been able to stop the leak(s) around the double doors. I cleaned the area, sprayed around everything penetrating the shell, no more leaks.
