My glossy black DF appears to have clear coat over the tape on the tank and fenders. I tried starting to pull off the tape with my fingernails but I can't get it started. What am I doing wrong?

Anybody come up with different tank ideas?
Here's one on Ebay that might fit. 3.3 gallon capacity.

Need to spend some time at a bike junk yard to do some looking for a tank.
