can it be used in glass? like fish tanks?

Asked by: helpme
You've come to the right place! We don't recommend applying Rust-Oleum Stops Rust LeakSeal Spray on surfaces that will be immersed in water. This abrasive environment will cause the coating to blister and peel off.

Happy to help! Rust-Oleum Stops Rust LeakSeal Spray is suitable for use on concrete surfaces. Please keep in mind that this product is not designed to provide reinforcement as a concrete patch would provide.

Can this product be applied when the temperature is below 32 degrees?

Can this product be applied when the temperature is below 32 degrees?
Asked by: Charles
I bet you can, as the leak seal developers claim it can withstand low temperatures. Maybe it will take longer to dry. ( It a woman's, mine, opinion LOL)

12 oz. LeakSeal Black Spray is rated 3.3 out of 5 by 60.

Used it to seal the inside and outside of a pond shell as there was a small leak but I couldn't locate it. Used 3 cans!!! Shell was cleaned and dried, spray was properly applied and allowed to cure as directed on the can. Within 72 hours the pond was empty again. In addition, the pond developed a white film inside it except for where something was touching the shell.

Rated 5 out of 5 by from Better than Flex Seal! Months ago, I saw Flex Seal on TV, and gave it a try around some flashing on my roof. The spray pattern was nothing like what was on TV. It was all over the place and made a mess. I saw Rust-Oleum's product this past weekend and decided to give it a shot. Wow! What a difference! It works as advertised and I know it will be backed by the Rust-Oleum name. The odor is a little strong, but for what the product is (spray rubber?), it is not that bad.

I am very pleased with the durability and how its sticks to everything you use it on. I used it for my car and sprayed it on over Bondo, Fiberglass and rust spots it fill all little imperfections and dries smooth and looks great. I recommend it for use on what ever you need to seal. I do suggest that it should come in other custom colors on the shelf.

Plashed a little while spraying. 12oz is a little small amount. You go through a can rather fast. I used it to reseal around flashings on roof where vents come through. Easier than using a bucket or can of tar.

For some reason, I presumed that this product would perform as well as the "Flex Seal" spray. Wrong! I used my Flex Seal even when I thought the can was spent 10x over, still a bit more came out. Don't make the same mistake I did and cut your project in half at the half- can used point or your project may not finish, like mine. With the can and nozzle restricting flow of the last quarter of product, I realize all, of the interior cosmetic work I did was in vain. One- forth of my roof flashing at chimney will leak again tomorrow in the rain storm. What a waste of time and money. I am a 53 yr old woman, not happy to climb onto my roof in the first place. Product failure. I will never buy this product again.

Rated 1 out of 5 by from over priced and not worth the time i ordered this product as i thought it would help stop a small drip that i had from my gutter, no such luck, it kept allowing water thru and eventually peeled right off, even after following the instructions. it is a big disappointment as Rustoleum i thought, was an exce ptional product and a trusted name . i would advise just using silicone liquid or adhesive to stop seam leaks, anything would work better than this...

Rated 3 out of 5 by from WORKED ONCE, BUT NOT TWICE I used a can of Rusoleum Leakseal on the inside of two rain barrels to fill small cracks. I put eight coats on each crack, starting out with small spray amounts. It worked to stop the leak in one rain barrel, but it did not stop the leak in the second rain barrel. I used about a third of a can on the inside of each rain barrel, spraying it in timed intervals throughout the day. I was disappointed that it did not repair the crack in the second rain barrel. I may have been applying it on the wrong type of plastic. I plan to scrape it off of the bottom of the rain barrel, and use plastic roof cement (tar) to repair the crack.
