GorillaWaterproof Patch & Seal Rubberized Sealant Spray, Black, 16 Ounce (Pack of 1) - Seals Out Water, Air, and Moisture

It works great! Super simple even with my arthritis hands. I have trouble with my strength but this isn’t difficult at all. Not only does it seal, it’s also useful for glueing some things. Like my outdoor camera that slipped down and hanging by the wires.Durability is great, light smell not bad, and I’m able to use for several projects. All of my needs are kind of small projects but definitely needed attention.Of course we all wish it was a larger can, but this one is coveting all my needs at the moment.Will upload video of the projects today, provided no rainfall 7/18/25

I use this stuff inside 3d prints that I need to hold water. No, Calm down, I don't use this to make things food safe or anything. I use inside of things like paint water cups or airbrush cleaning pots. I use it for small planters to protect them from the water. Just things like that. I have made the mistake of spraying it in the house once, it'll never happen again. This stuff is pungent. It's easy enough to apply and it works well for my purpose. It seems to last a while, I've been using things I treated for a long time and still no problem. It's crazy expensive though, so don't waste it.

I've used this product before and seldom have any issues. When i do, it seems the spray comes out more like a hose stream and not a spray nozzle. I shake the can constantly to try to avoid this and it's probably the makeup of the product. Nonetheless, this project was to seal any rust areas in this old HVAC overflow pan rather than spend $400 to replace it and the product sealed the pan as planned from what i can tell. I've used it inside gutters as well when the joints leak with age and it seems to cover and hold up well.

0 stars out of 5. Doesn't work I wasted a whole can trying to fix a crack in a water fountain and after 5 thick layers it's still dripping water. Look for another product. I only put 5 stars because Amazon puts the 1stars reviews all the way down.

Excellent product...used it on bird bath...no leaks after spraying liberally.

Used to seal a planter for the yard. Instructions were clear to use and apply without any mess. The canister allowed me to apply multiple coats for good coverage. Purchased with a good sale price so a good value for my purpose. Appreciate how the planter will be protected.

Used the whole can on a leaking concrete fountain with a thin little crack. Did multiple thin coats, did not work at all

Good price, as described dries clear, easy to use, i tried this now to see if it holds!!
