Pros & Cons
Pros
The product is essentially a silicone product similar to silicone sealer caulks. It brushes on easily and is easy to clean-up the brush. I even use spray flex seal on wood fence posts before burying them in concrete so they dont rot off at ground leve... Read More
Grey flex seal is perfect. Clean the crack, and put flex seal in till the crack is full. No more rust.
Cons
Lousy quality control for a fairly pricey product. No mention of the badly mismatched gray color problem. This seller is pitiful. This is way to pricey for little amount it comes with.
It looks great, but it didn't adhere to the surface. It peals off at the slightest touch. When attempting to repaint, it shrivels and creates a terrible mess.
Highlights
Quality
Outstanding product: solved the water leak problems i had on my shed.
Flex seal liquid works very good it seals and did not take long in drying it's the best.
This product dries to a hard rubber consistency.
My cement bird feeder was leaking; pained it with this and it no longer leaks!
Price
I bought a cheap $200 quick set up pool, by the second year to no ones surprise it had a couple pin holes in it.
A bit pricey but served the purpose.
The price probably went up 5$ as i was typing though.
Competitiveness
Above and beyond compared to most companies.
I tried the flax seal spray 1st but it didn't do so well.
