The x-flock shrink wrap stuff is very nice and goes on easily over cork tape. Mudhole has it. It is easy to apply with a heat gun. It shrinks primarily radially and only very slightly longitudinally. Cut it a little long and trim it after you shrink it.
The X flock shrink wrap is better than cork ,,. yes better .. It's not abrasive to the crotch of your waders like cork tape is .. like if your working a pencil .
The flock is awesome but I had 2 rods wrapped with the colored stuff from mudhole and it cured like a hard plastic and it sucks. I'm going to have them done with the flock over the winter. I thought it was the same stuff but it wasn't.
