Flex Paste Super Thick Rubber Paste, 8.75 fl oz, White

I had to cover up a couple of cracks so water wouldn't leak in and the flex tape helped keep the water out, it's a great quick fix. I suggest getting a putty scraper that's narrow enough to fit into the tub. Apply a thick enough coat, let it dry fully for a full day. Go over it the next day just for extra coverage. You have to read the directions and keep the foil on it and silica gel packets so the entire tub doesn't dry out. This is very important. It's a good price and I had some left over just in case I need it in the future. I recommend it!

I bought both Flex Seal spray and Flex Paste at the same time. The Flex Seal spray worked great, and turning the can upside down and spraying until it clears after each use allowed me to use the spray, a little at a time, over a 2 week period without any clogging. The Flex Paste came with about an inch thick ring of the paste hardened at the top. Using the suggestions of leaving the remaining paste level and resealing with the protective foil and silica pack allowed me to use a little at a time over a two week period without any further hardening or waste. Luckily I didn't need that amount that was hardened when it was delivered. But yeah, it worked great layering it on every other day, allowing each layer to dry between coats.
