So like many of you fine guys and gals here I have decided to remove all warning labels off the gas tank and a decal the previous owner of my rebel put on. I removed 95% of it all and there is nothing that catches when I run my fingers on the tank, it’s smooth, but the decal from the previous owner is still faintly imprinted on the tank. The method I used is a heat gun, WD-40, and a microfiber cloth. Is there another fluid/product I can use to completely remove this imprint?
