I was at Home Depot - couldn't find the PVC Pipe Tape - perhaps it's the wrong time of the year??? I'm interested in comparing it with the 2-3 layers of a high quality duct tape, I've been using on my keel line for years. It seems effective enough to protect the keel and definitely cost effective. When it wears/tears, I just replace it, sometimes only the outer layer but I'd like to find a longer lasting tape, if I can.
I'll keep looking, but welcome any other prospects, too!
