Gorilla Waterproof Patch & Seal Rubberized Sealant Spray, Black, 16 Ounce (Pack of 2) - Seals Out Water, Air, and Moisture

This is now the third winter since I applied this sealant in several places on an aluminum storage shed. I live in an area of arctic type winters and rain forest summers. Three years and it is not showing any signs of degradation. NO LEAKS. NO CORRESION around the patched areas. It has yellowed just a little bit but I do not care about that. I even used a little to seal up a hole over a wood patch at the base of my garage wall to keep the field mice out. I don't think the little critters like the stuff much because they did try to chew it a little at first but then gave up. That was the summer of '24 and the patch is still there....and the mice aren't.

I purchased this Gorilla sealer to stop a leak in a gutter. It worked perfectly. It was so easy to spray on to seal the gutter seam. I sprayed it while weather was warm and dry when there was no threat of rain for a few days. I will definitely purchase it again when a need arises.

Review: I recently tried out the Gorilla Waterproof Patch & Seal Rubberized Sealant Spray to patch up some tiny rust holes in my gutters, and here's my balanced take: Pros: Ease of Use: This spray is incredibly easy to apply—no messy brushes or applicators needed. Just shake, spray, and you're done! Versatility: It works on a variety of surfaces, including metal, concrete, wood, and more. Perfect for sealing gaps and cracks in gutters, roofs, and even outdoor gear. Quick Drying: Dries relatively fast, allowing you to move on to the next step of your project without long waits. Self-Leveling: The formula levels itself out, ensuring a smooth, even coat that covers small gaps and cracks effectively. Cons: Multiple Coats Needed: For optimal results, you might need to apply multiple coats, which can be time-consuming. Runny Formula: Some users found the spray to be a bit runny, which can affect its performance on vertical surfaces. Clogging Nozzle: The spray nozzle can clog if not cleaned properly after use, making it less effective over time. Tacky Finish: In some cases, the sealant remained tacky even after drying, which can be inconvenient. Verdict: Overall, the Gorilla Waterproof Patch & Seal Spray is a handy product for quick, reliable fixes around the house. It worked well for patching tiny rust holes in my gutters, sealing them up nicely. Its ease of use and versatility make it a go-to for minor repairs. However, be prepared for potential issues with multiple coats and a runny formula. If you're looking for a straightforward solution for sealing leaks, this might be worth a try, but keep in mind it might not be perfect for every situation.

Worked great for what I wanted it for. I used it to make a fire pit for Halloween

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.

Ordered these to re-paint my metal gutter. Prepped the old gutters and started painting. Now, I know most spray paints can run and drip if you go with too strong of a spray, I usually take it easy and do multiple coats with light, broad strokes to eventually get good cover. However, it was very hard to control the spray with these cans. No matter how controlled I tried to be, the paint would still leave runs and drips. In addition, the nozzle started to clog when I was only about 1/2 way through the can, which meant when I tried to do a controlled spray, instead of spraying, it would start dripping from the nozzle onto my hands, my ladder, and the ground. If I tried to gradually increase the spray, it would suddenly spurt in a strong stream that would overshoot the gutters onto the roof. On a positive note, in my testing, the paint does truly seem to be waterproof and performed well in that respect. Bottom line: waterproofing works, but seems that it would work better on horizontal surfaces; vertical surfaces are too suspect to runs and drips.

This stuff is awesome. Very easy to use. Looks nice and creates a nice seal

I used it outside around my basement window and it sealed properly
