Spray Rubber Sealant Coating, 14-oz, Clear (2 Pack)

Not good

Lo use para cerrar una grieta en la pared pequeña y fue muy util.

Hasta el momento ha cumplido con mis expectativas

I've used the clear coating a couple of times on my outdoor lawn wagon to protect from the elements and other items that might sit out in the weather occasionally. It really helps keep them from rusting, scratching & deteriorating as quickly so it's worth it for me.

I've actually bought this product several times already, and will probably do so again in the future. I'd seen ads where the pourable type (in black) was used to line a garden pond showing that it was safe for koi and goldfish. I used the clear spray-on to line a large galvanized tub to create a mini pond. After a month under water the Flex Seal is holding strong, and all my fish, tadpoles, snails, clams, and plants all seem to be quite healthy and happy! My only complaints are two small issues. The first is that in order to get the coverage I wanted, one can only covered a space of about 18x24 inches -- or 3 square feet. For the cost per can, I would have liked to have gotten more coverage than that. The second problem is with how the spray set up once it was applied to the metal. Initially it seemed to flow and adhere well, settling with a smooth surface; but after a few minutes, tiny bubbles rose to the surface and left hundreds of little pits all over the top of the product. I was hoping that additional layers (after each layer dried) would solve the problem. They did not. If anything, the bubble dimpling became worse with additional layers. On most any other project I would probably overlook this issue, but because the tub is outdoors in direct sunlight for several hours each day, algae has gotten a foothold in these little pits causing the old-fashioned grey metal to turn lime green. I will say that perhaps the pourable Flex Seal might have been a better choice for this project to avoid both of these issues. At this point, I have no idea. If I do try that in the future -- which is very likely -- I will amend this review to reflect any differences. Photo 1: July 30, 2016 - tub cleaned, but without any Flex Seal. Photo 2: Sept. 24, 2016 - Happy inhabitants, but walls are green. Unfortunately, I forgot to take photos before final set-up.

This review isn't really testament for sealing roofs, or screen doors against water. I purchased this to use more as a "rubberizing" and water barrier sealing spray. I wanted to use it to seal some raw steel to protect and prevent it from rusting out in the garden. So far it's done it's job of sealing out water, but it also looks like plastic coated metal, rather than metal with a clear coat. I'm going to leave it for now to see how long it prevents rust, but eventually plan to remove it and try something else that looks more natural. Some other things I wish I had known before buying that might be helpful to you: > It does NOT have a "delicate" nozzle tip. When you spray this, it sprays out fast and hard. There's not much "feathering" you can do. > As it sprays, some of the overspray will turn into little airborne rubber "floaters" that have a tendency to drift much farther than just regular over-spray. It's almost like little gossamer web tendrils. So make sure you take this into account. > There are other spray rubber products that are available that act much more like spray paint. They are meant to coat and not really seal with the tenacity of this Flex Seal. — That's not to say that Flex Seal, doesn't do what it's advertised to do — I'm just saying that if you're looking for something to use to create a smooth rubberized coating on something, you might be better off with a different product, Like Krylon. > the price was better for this than other rubber coating sprays, (which I have not had much luck finding in my local Home Depot or Lowes stores) >As a water sealer for cracks — I also tried to use this on a large, clear plastic rain gauge that had developed some small cracks, resulting in a slow leak. I sprayed several coats of the flex seal on it. It didn't work. And because it doesn't have a very smooth or fine spray, it went on with such a dimpled effect, that I couldn't read the numbers through it. Maybe it works on roofs and turning screen doors into boat keels, but it didn't work for me for sealing small cracks to prevent the force of a couple ounces of water at bay. It might have been different had I tried to spray it into the inside of the rain gauge. But seriously, thing about it... you're just not going to have any kind of permanant effect on a roof repair, for instance. As a stop-gap measure, maybe.
