I tried taping around the rubber or plastic seal that the glass is set in, but still leaks. Then I saw a Flex Seal commercial on tv and the video up first was sealing a windshield with the "clear" type of Flex seal. After taping all around the windshield with blue painters tape, as you don't want any spray getting on the painted part, I put 3 coats of the "clear" Flex Seal above and below the windshield's rubber seal. Wait about 4 to 6 hours between applying the coats of the Flex Seal. I tested the seal this morning with my water hose...... NO LEAKS ANY WHERE !!!! THIS STUFF WORKS !!!!!! Thank you desertcart FLEX SEAL IS A WINNER !!!!!! Review: Definetly keeping a can in the camper now - I purchased this 14 oz can of white Flex Seal to repair some cracks on my popup camper’s roof after I accidentally backed into a tree. I was worried about the damage, but this product ended up being the perfect solution for the situation. It went on very easily, and I’ve been impressed with how well it holds up; after 34 days, there are absolutely no signs of peeling or poor adhesion. Most importantly, I haven't seen a single leak from the repaired spot since I applied it. It’s also incredibly discreet, as I can hardly even see where the damage was anymore. It worked perfectly to hide and fix my mistake, and I’m very satisfied with how it turned out. ## Features - The easy way to coat, seal, protect, and stop leaks fast!

However Flex Seal Liquid is. We have never tested it for this use. I'm not sure it will take away the odor since there will still be a hole in the cat box for the odor and cat to escape. **Q: I am trying to seal a water fountain. but i want it to be blue. can i use the flex seal liquid first and then spray the blue flex seal for color?** A: I did not use the flex seal liquid, but I did use the blue flex seal on an inside pond, and it has held up very well **Q: How many cans do I need to paint a canoe?** A: Not sure exactly but a can doesn't cover a large area depending on how thick you need to apply it. We used ours for smaller areas and it worked great! ## Customer Reviews ### ⭐⭐⭐⭐⭐ GOT WATER LEAKS, FLEX SEAL STOPS THE LEAKS !!!!! *by H***Y on July 29, 2026* I used the Flex Seal on my 21 year old GMC pickup truck where when it rained it would leak the rain water at the driver side of the windshield.
