I convinced one of my contractors that had been using CWF on his projects to give Ready Seal a try. He came back the next day and thanked me for the heads up on this product. My contractor applied Ready Seal to some Cabins, he commented that it was easy to use and it did a much better job than the CWF, it saved him almost 60% in labor cost. I highly recommend the ReadySeal products to all ABS members.
