That's great David, I used to wax my car 3-5x a year for something to do but when it came to covers I never thought of that, I just got another. I have a Ducks Unlimited cover for my KK, it's 7 years old and the only one I've had for the KK, it still works although it's parked under the deck. You've got me thinking, I remember when it was new it would repel water just like a finished wax on the car, it still repels water but it doesn't bead water like it was new, I believe that memory has passed...at least for covers. Good idea, shake the tree, I'm in for a can.
