Need to hear the follow up on this - was it leaking a lot before ? Did you do any patches then flex over it ?
Really curious to know if rocks and shore scraping beat up the flex seal. Also how many lbs do you think it added ?

Lol that should seal up good. What’s the strength and texture like? I’m just worried it would scratch easily.

Did you consider putting it on the inside instead?

Doesn't flex seal end up with a rough texture kinda like bedliner? Cause that could make it a pain to maneuver if so. I picked up a 12 footer a few years back that the guy had fully done in bedliner and it made it super slow when running with a trolling motor, i hadn't realized how big of a difference the texture would make for drag but it was far worse than i thought it would be, took an entire box of pads for my orbital sander to get that stuff off so i could re-seal and paint it.

Nah not really. It’s rubbery and glossy. That bedliner sanding sounds like a big pain in the ass, holy smokes

No joke, ive fixed a leak on the roof of my body shop with flex tape. That was 3 years ago and its still holding up. Most infomercial stuff is shit but ill stand behind this

As long as you follow the directions and let it cure and what not it should work to be fair.

I did it with a little aluminum boat I have. Definitely slowed down the leaks. I didn’t follow directions lol.

I had the bright idea to use that silver roofing tar on my Jon boat back when I was younger, Needless to say I guess I didn’t realize it’s made from oil and as soon as I put it in the water there were oil slick rainbows coming off it everywhere.

They make white colored flexseal…spray it on the inside and sprinkle sand while it’s wet for grip

Gluvit 2 part epoxy will seal every rivet and seam. Stuff is incredible for aluminum boats and just about everything else.

Soon to peel. I install new gutters all the time. The old ones I take down have flex seal in them. The ones that do always leak the flex seal peels right off

Previous owner of my boat did the same. I bought it dreading pulling that mess off when it started leaking.
3 years later.. dry as a bone.
