I have used this in the paste tin format, and it is awesome. Having in a caulking gun format only increases the amount of awesomeness.

This is the only product that I could find that I could use in a outdoor fountain that has a thick EPDM GoodYear made liner that would stick, and that was safe, out of all the other products on the market. Thank you

This product is great! I have used it in the can and the tube on my rubber driveway to keep the edges from lifting. Yes I would recomend.

My cars roof has some pretty bad rust, finally it started to leak. So before winter came I decided to seal it up with this. To my surprise it works really well lol… not the best thing to use on your roof, but it’s the quick and easy repair for an older car. Not the way I wanted to repair it, but it does the trick for now!

Work well. Seals great.
