OSI GS121 Gutter and Seam Sealant Clear, 5 fl oz

I needed to relocate a gutter outlet and patch the original location. I used this OSI sealant to seal the new outlet and the seam around the patch material. It sure seems like regular old rubber cement to me, but maybe it has some additional chemistry that I'm not aware of. But if it smells like a duck and flows like a duck,,,Anyway, can't speak to longevity yet but it worked perfectly after a few strong storms within weeks of being installed.

Had to redo the seam tape on my porch roof and use this to reinforce and cover up screw heads and it worked perfectly for the job.

We had dripping from the seams of our gutters when it rained. My husband tried everything on the market to seal the seams and prevent this. I purchased this after reading some reviews. We finally have NO dripping from any seams when it rains. A great product and I know it works well as it has been raining here off and on for about a month now. And some rain is torrential. Buy this!

I ordered a oval picture each of mom & dad to put on their grave stone. Did a little research to find out how to attach them an make them stay. This is what I found to be the best and it worked perfectly, it’s transparent so I let a little one the sides which you can’t see. Very happy with this product.

Best dang glue I’ve used over the years but takes forever to set. I use this glue for setting polycarbonate in enclosures. No matter how long this glue is exploded to the elements, I’ve never had it get hard and brittle or cause a leak. If you’re looking for something that will never get hard and brittle, this stuff is what you need. It is removable too which I also like but requires a lot of persuasion though to come off.

Love this product. Superior to super glue. The cap setup prevents any waste. Some smell so need ventilation recommended.

nice stuff

Read and follow the instructions and it will perform like a champ.

Works good for my needs
