Review: Top Notch Stuff! - A friend was helping with my barn roof. He told me I needed to get something for the fiberglass panels that were 45 years old. I picked this out because it sounded like it would work. He started painting this on one of the panels and yelled down, "This is great stuff! Where did you get it?! I can't believe how good this works!" It darkened the panels, but the same light came in from them inside the barn. A super coating! You must be very careful when using this because the vapors will do a job on you if you are not careful. Good masks and a nice breeze work perfect.
Review: Restores dried out shingles - I had a spot on an older roof that needed to be replaced but I was planning on replacing it in a few months when the weather was nicer and i had the time. This stuff did a great job helping reseal the area where water had come through during a heavy storm. It smells like rubber cement and seems to have a slightly runnier consistency. With these shingles being extremely old and dried out, it didn't spread extremely far but filled in every gap quite in the granules nicely. I was able to use a brush to push it around the whole area. It's similar to putting on a thick asphalt sealer on a blacktop driveway but it is clear and made for shingles. Since the shingles were old and a lot of the connective material has disappeared, you could definitely tell a difference as it made these flat instead of the dried out granular top. The whole section where I put it looks much shinier than the old section. It probably brings it back to looking like a new shingled area. It did the job to seal it quite well; it's just definitely noticeable where you put it on an old roof.

## Questions & Answers

**Q: Is it possible to paint over it?**
A: Yes. You can paint over our LeakFix as it works effectively as a primer and sealant. So you're assured that the walls are clean, crack-free and primed well before painting or prepped before wallpaper is installed.

**Q: Can I use this for the bottom of my pond?**
A: Although it is great for providing waterproof solutions, Polar LeakFix is not recommended on surfaces that are underwater. This may be toxic for aquatic life when applied to ponds.

**Q: Is Polar LeakFix resistant to harsh weather conditions?**
A: Polar LeakFix is designed to provide resistance against the harshest weather conditions, ensuring a reliable solution for a wide-range of surfaces.

**Q: Is Polar LeakFix resistant to harsh weather conditions?**
A: Certainly. Much like with PVC, you can apply our LeakFix on polycarbonate roofing.

**Q: I accidentally sprayed my hands and some parts of my arm, how do I get rid of it?**
A: Remove splashes from skin with a hand cleaner or plenty of soap and water.

### ⭐⭐⭐⭐ Large gaps require several coats.
*by Y***A on October 25, 2025*

Small gaps seal ok but wider openings require several coats. Be sure to let it dry between coats.
