Welcome to our forum.
Great idea Vinny, it's the stuff I use for my fish tank right? Smells like acidic acid?...It will probably look awlful but I am afraid of leaks into the cover. The cat just dug right in and pulled on the vinyl I am going to get that sticky stuff because as long as it doesn't wreck my tub cover, it can hang out and chase my chipmunks!
Wonder why it picked the hot tub to roll around on?
