Flex Paste - Fixes Shower Tub/Leak

We've had an on-going problem with our 20 year old fiberglass/gelcoat shower/tub. The leak started as a small hairline crack in the bottom and has grown to 2-3". Over the last 3 years I've patched it twice with the Gelcoat Repair Kits which last a while, but begin leaking again. I did some research and decided to give Flex Paste a try. I covered the leaking area with Flex Paste and have been leak free for a couple of weeks. It seems like a solid repair and we'll see how long it lasts. I like that I can spread the Flex Paste well beyond the crack.

Coated Rusting Support Steel

I have a salt water pool and the coping support steel at the catch basins was rusting and flaking into the pool. I used flex paste to coat and seal it. Problem solved! #Flextacular

Used it on everything!

[This review was collected as part of a promotion.] Flex Paste Clear really lives up to the hype — my dad used it on everything, and it actually worked. It dries clear, creates a super strong waterproof seal, and holds up great over time. Whether it was fixing leaks, sealing cracks, or quick home repairs, this stuff handled it all. Definitely a must-have for any toolbox.
