Flex Paste Industrial Sealant, Thick Rubber Paste, 8.75 fl oz, Black

As with all of the Flex products I have used, I am very pleased. One of the best parts about this paste, is it can be used on wet, not so clean surfaces, making on the spot repairs in less than ideal conditions possible, whereas the spray and brush on rubber sealants work best on dry, clean surfaces. Also, as with all Flex products, as long as the container is well sealed, it should last indefinitely. Once opened, I would slip this can into a zipbag just to be sure, as one of the two cans I ordered was already dried out, completely cured and will have to be refunded. Speaking of cure, rock hard! Since this is my first time using this product, durability is yet to be determined. Will it get crusty, cracked or sticky over time? We shall see. But, as it stand now, I love it and will most definitely use it in the future where applicable.

The product is great but I had to buy it from Lowes. Two times I ordered this and the packaging was basically non existent. Both times it was damaged, air got in and it dried out to a solid hockey puck. Buy it in a store.
