Flex Seal Flex Paste 3lb (Black) Tub with Allway Tools Putty Knives 3-Pack (1.5/2/3-Inch) (2 Items)

Worked out well

I purchased this in Jan 2022. I had never opened or used it and went to use it today Dec 2023. I realise it is nearly two years later however I had never so much as even opened the lid. When I opened it the product had set within the tub. The foil liner inside apparently does nothing. I also had this stored inside a sealed plastic crate inside my garage so the sun had not been hitting it. So I paid 103 Australian dollars for a lump of unusuable rubber.

This stuff really works. It sticks tenaciously to everything and is watertight. Cures fast. I’ve used it twice now and will not use anything else when I want to avoid leaks. Dropped one star because it arrived with a layer of cured material on the top of the new unopened bucket so 20% was not useable.

I sealed up a 2016 Freightliner Cascadia. The truck was leaking between cab and roof. It's a on going problem with this cheaply built truck. Sealed it up good. Taped the seam up put sealer in seam pulled tape after set for 1hour.

Repaired a pair of my tennis shoes. (soles were peeling away)
