Stopped the leaks
This product worked great on my pond's waterfall. It does take awhile to cure - says so on the bottle - yet when it does, it's strong and secure

I have received this package.
To Graystone Creations I'm sorry for the mix up after looking at the can again, it is a 16 oz can. Again I'm Sorry!

Don't buy this product
More than half of the can I purchased was waisted after it ran out of gas to spray it. I will never purchase this again.

Slow expansion, but big
My fault for not testing it myself first. It goes on a bit small, expands over the next hour immensely. It got a bit out of control. I wish I could have laid down a smaller line with more control, but the straw doesn't have that kind of control. I ended up using far too much far too fast. It ended up ballooning out of the area I was working.

Good "black" foam
I have a dark grey and black colored RV. All the voids and seams are sealed with a black foam sealer. I found this "black" foam (used as in pond and water environments) to be a great alternative to the everyday light colored big box store window foam when using in an environment where the color would bee more esthetically pleasing.
