GREAT
Fantastic Product For Water And Air Sealing Around Windows And Doors

I use this product a bunch and really like it. It does take a while to learn just how to work with it so it is perfect. It does take longer to use than sticky tapes, but I feel the quality is much better.
I wish they had different options when ordering on Amazon such as quantity amounts to help save on shipping. For example, order in increments of 5.

Better than the Roll-on Version

I have utilized the Blue "poly" brand stuff and Prosoco products, there isn't much comparison - Prosoco is a much better product.
Whether you're are comparing tooling it on, the adhesion, or resilience - Prosoco is easily the winner. This is comparing my experience using both products over the past few years.
Not going back to the blue, Prosoco is by far the better product.

Easy to use. Great insurance

I used this to flash where an exterior wall met the foundation that protruded beyond the face of the wall. I also put metal flashing over it, but I feel much better knowing there is a barrier beneath my metal.
Easy to use in remodeling, when plastic barrier can not be used
