Flex Seal Liquid Rubber Sealant Coating, 32 oz, Black

Have used this product before. Haven't had any problems.(haven't tried sealing a boat, yet?) ; ) That said, If your thinking of going back over your work(aka second coat). Better to wait til it dries. So, you get a smooth look(looks better) Just saying. ; ) So, Yes I would recommend this product.

It's works just as it said it would….. I suffered with a leak during rain on my sunroof and when I say 10/10 it's 10/10. Now I recommend using gloves or something to protect your hands because it's a hassle to clean up if you mess up

used this product to seal around outside items on my rv. like the compartment doors , stove vent etc. works like a charm. make sure you wear gloves when using this product

Although I get a 10% discount at a home improvement store the Walmart store was 10% less and they had same day delivery from a store. I have to depend on public transportation which meant I could not order from Walmart until I realized the Walmart price plus the same day delivery made it a great deal and an automatic yes.

I basically just needed to rubberize a slippery surface, and it worked out great. Really, once you understand exactly what this is and does, it's good for a lot of things besides waterproofing.

my husband and I like this product because it sealed a leak on our boat so we keep a can around the garage.

This has worked great - I put it on a metal trailer to help stop rust and it covers the areal nicely. Takers about 48 hours to set up and looks great.

Didn't like them being delivered from store. First one was crushed. Had been dropped during delivery in a counter bag and top corner of can was crushed in. Next day received replacement can delivered from store and was wrong color. Someonr juist picked up a can of Clear, not Black as ordered and delivered it. Wouldn't accept return on line. Said that I had exceeded the return date. Just bouight it the day before delivery. Had to load both cans up and return to a store the next day for refund. Then located the product display area in the store and bought a new undamaged can of the proper color myself.. Could have saved three days by going and getting it myself to start with.

I have no idea how long this item sat on the shelf at the store but the first thing I noticed after delivery was that the label on the can was an older style label. After shaking the can vigorously for over ten minutes I removed the lid and dipped the paint brush in it. What came out on the brush might best be described as an oily substance. I then tried stirring with a stir stick and then was when I realized this stuff had been on the shelf too long. Roughly 1/4 of the contents had already set up. After scooping the bad part out I proceeded with my project. It appears everything will be fine but spending $40.00 gives the spender certain expectations. After previously spending $40.00 at Lowes for the same thing and being very well pleased with the outcome, I wound up needing some more and, due to time restraints, I ordered some from Walmart. Time will tell if I regret this move but with my not being a very patient person, if Lowes has it, Lowes will get my money. Incidentally, I'm building a wooden outdoor structure that I hope will not succumb to the weather in middle Tennessee or the carpenter bees that giveth no damns as to whether the wood has been painted, stained or epoxied.

I opened it and it looked like it had been opened for a while. when I tried to stir it up there was a hockey puck on top and it was almost half the product solid . walmart did refund me . I have never seen that before.
