Ok, so I hit the tank with some heat from a hair drier and actually did not need the fishing line, it peeled right off thankfully. However, on the matte paint, there is a "shadow box" of the sticker. I tried washing it off, but it isn't the glue, it looks just like the paint is a different color. Any suggestions? A friend of mine stated more than likely will fade due to sun. It isn't extremely noticeable, however, when I look at the tank now it is all I see....
