Polar Premium Instant Waterproof Roof Sealing Paint for Leaks, Roof Seal Repair Coating Paint for All Roof Types and Gutters with Reinforced Fibers

The product works great. I had two water leaks and I brushed the leak fix in the area on the shingles and we had a rain the next day and not a drop leaked in. Thanks

This was applied to a felt roof which had had a small leak - being transparent, it doesn't seem too obvious but it does add a more reflective coat so does show under close inspection. Paint consistency is very thick, making it easy to slather on as per the instructions, while giving your brush hand a good workout! The surface remains sticky after drying so will tend to collect debris more. However (touch wood) it does seem to have worked so far in fixing the leak. The product safety warnings should be carefully observed. Even while wearing a facemask and outside, the fumes were noticeable. This is very much an outdoors product.

Worked great for sealing my bathroom sink. I hope it also will be work on our metal roofing as it also leaks bad.

Fixed up a hole on the shed roof with this, secured the area and avoided any more water damage

Worked well !
