After 2 years of having masking tape on the canopy and windshield, peeling it off left a glue behind .
Well after extensive research on the RV lists, it turns out an off the shelf product Goo Gone does the trick, and safe on the canopy.
More pictures to come. One item of note. Don't leave this stuff on the glass any longer than is necessary to get the glue off. It leaves a haze into the glass which gave me a heart attack. I mean real panic ville.
Plexi glass polish and some cheese cloth took the haze right out, but not after a few more grey hairs.
