Toy wheels coating
My use of Flex Seal is unusual. I needed something to put on the rear wheels of a wooden toy so the wheels would rotate instead of sliding on slick surfaces. Flex Seal is working very well for this purpose.

AMAZING
I bought this to seal a leaky bay window that went down to the floor. I only used one coat and worked beautifully. The only negative I'd say about it, is the price. I bought the pint and thought it was a little pricey but otherwise it probably wouldn't keep me from buying it again. It just worked so well.

Great Product
I used this product on the inside of weightlifting collars to give them a slightly smaller diameter and a little more grip on the bar. It worked great although it is just a little bit thin to brush onto sloped surfaces. It tends to sag, droop, run etc. mostly by it's own weight I'm sure. that said I am so impressed that this is liquid rubber that drys tough and is actually white! I have some window problem and I plan to brush Flex Seal on the really bad spots to keep water out while I search for a fix. It would make a great sound deadening or sealing layer between surfaces etc. This is a dream come true.
