Rescue 911 Multi-Purpose Instant Leak Sealer - Black

My husband has used this on minute leaks in out roof where the screws go through. These are areas that are usually impossible to get at with conventional products, and this is easy and fast. Only be very careful to clean the spray nozzle after use or it will plug.

I went to use this leak sealer , and all it did was spit out a few bits of black gunge and then it was blocked, so I could not use it for what I wanted. I had to use the clear can of the same item, which gave me no problem at all, the only thing I thought it might be was that it seamed thicker than the clear. I have chucked it in the cupboard untill the summer when the warmer weather might be better, if not it's going in the bin.

An awesome product that I have now used on several roof applications and it worked every time. Just about to make my 3rd purchase of this product.

A very good product, does exactly what it says on the can, cured the small leaks. This maybe short term but we will wait and see.

Unlike another brand I tried this worked a treat
