Polar Specialist CoatingsClear Leak Fix Paint - 35 oz - One Coat Waterproof Sealant with Reinforced Fibers, Instantly Seals Leaks & Cracks for Roofs, Drainpipes and Gutter Repairs for Exterior Use

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

this product took care of every leak i had on my metal roof. highly recommend this product. when i applied it i put it on with a paint brush using strokes across ways and then up and down strokes. it works great

Used this to prevent water from coming into my basement and works just as said!

This fixed a gutter leak at the corner after one application and multiple failed attempts with flex seal. I used clear. It is thick, sets quickly, easy to apply with a disposable paint brush.

I put this on my trailer house roof to eliminate leaks. It's helped so far. I don't mind living in this trailer, just don't like leaks. The gal on lot 3 has a very leaky roof but she didn't try this so she still leaks over there. Maybe I'll tell her about this product if she will stop talking about her in-laws all the time. I can only take so much when people aimlessly talk about nothing all the time, I mean I've got better things to do with my time, like fix leaks on my trailer

I bought this to seal up six leaking seams in rain gutters. My problem was gutters were 24 feet high and I had a 16 foot ladder, so you can do the math. The paint brush I used on a 8 foot pole could not apply this sealant with enough pressure to be effective. You really need to put his on with heavy brush strokes loaded with the sealant and unfortunately I was not in the position on the ladder to do that heavy enough. After sealing up six seams with one coat, it rained 48 hrs later and all seams still leaked. Im not giving up on the product. I'll try to heavy brush it on once I rent a 28 ft ladder. But, to be effective, I believe you have to brush it on from a foot away with heavy pressure strokes and lots of the sealant on the paint brush. Also, its real sticky so wear disposable gloves to make clean up much easier.

Applied to chimney flashing leak. this stuff finds holes and seals. Thin and flows enough to get into cracks yet thick enough to control where you want it. Used many different roof patches and sealers, this one beats everything. One application, no more leaks.

The product works fine, however the top does not seal properly even using the provided clips. Not sure yet if product will dry up in can. The top is definitely poorly designed when you can't get it to seal properly like a paint can.
