I am getting ready to put a rack together and I am going to use flex watt. I have heard you need to protect the flex watt from the constant rubbing of the tubs sliding in and out. I am going to use 4 inch flex and I have some very thin aluminum flashing that is cut to 5 inches wide. I was thinking of taping over the heat tape with aluminum tape do you think this would be a good idea?
Thanks Richard
