has anybody ever tried Flex seal on the seams of there pop up houses? my last couple of outing's have been wet sticky snow that accumulates on top and with a heater going it melts down to seams and drips inside the house. I have a tarp that I have used that helps but kind of a pain in the butt. its not just my ice house that has this problem my friends last weekend had same problem. I looked at flex seal's web page and did not see anything about using there product on any type of fabric. i have looked at other sealers and it looks like it would be a multiple application process. looking for a good fix any info appreciated.
