Stuff seems just like Rubberizeit but in spray cans...Hummm... I can't speak for this stuff but I can for rubberizeit as I used that for my main sealer on my DIY plywood build and that was pretty easy to work with. As far as how it works...We'll find that out this week when I do my first test fill. Only thing about this flex seal that I see, is the spay can application and the fact it's $20 a can... It would have taken hundreds of cans I'd think to do the same size tank I did and seems better to buy in gallons and roll on IMO for larger tanks, however this may work well for smaller jobs like small tanks or sumps. I'd be interested how it works, keep us updated if you deiced to try it out!
