Flex Seal™ liquid stops leaks fast! Just brush, roll, dip or pour this thick liquid into cracks or holes. It quickly dries into a super-strong, flexible, rubberized coating that forms a watertight seal. Works in extreme heat or cold and lasts for years. Prevents rust and corrosion, and is paintable, too. Great for tools, sports gear, RVs, roofs, gutters, basements, pools and more. UV, mildew and chemical resistant. 16 oz. can.
Small quantities = too expensive
Quarts are too small a quantity for sealing roofs! Should also come in gallon cans and 5-gal. buckets to save price on packaging!
I wanted to repair a faucet hose...this didn't work. I gave it to my grandson so he could dip his tool handles in it. (or whatever he wants it for)
