    I used this product for commercial and personal use, in cold weather and hot, and it always performed flawlessly. It provided strong bonds with a variety of different surfaces.

  2. 5 out of 5

    This is the best product I’ve used so far. I used it on my roofs instead of tar-based products. It is easy to apply, holds very well, and it will be the only product I am going to use… I like that it is transparent.

    I applied your product to where my shake shingles meet the asphalt roof shingles and the snow sits, melts, and is absorbed through the bottom of the shakes. This was done last fall and the shakes appeared dry this spring… I also applied some on my chimney flashing instead of the black mastic sealer… I like that it is applicable with a brush rather than a putty knife…it is great stuff!

    I would recommend this sealant for most all applications. Being able to use it even in damp locations makes it nice. I like its ability to cover and seal.

  5. 5 out of 5

    Worked well on metal & metal roofing to stop leaks. Also worked well on asphalt patching… overall product is very good for difficult jobs.

  6. 5 out of 5

    I was really impressed with the versatility of this product. It can be used virtually anywhere…It did take time to apply because of its thicker consistency but I guess it has to be thick to be durable. It is easy to clean up and has minimal odor.

  7. 4 out of 5

    This spring I found a crack in my camper roof… (I used your sealant to fill the crack) I checked it out after we had a hard rain and high wind. there was no water or any sign of separation. It is very workable.
