If it were something that Harbor Freight just started selling, I'd be with you, but 3M?
I too wonder how well it works. Polyolefin heat shrink is pretty abrasion resistant, and the stuff with the hot melt adhesive inside is quite waterproof.
I wonder if this is tacky on the inside, like the butyl adhesive on the underside of flashing tape. That would take care of the water issue.
