Any chance you could post of photo of what this "eraser" looks like? My enclosed car trailer had vinyl lettering all over both sides, I spent hours trying to peel off the ols stickers and lettering, but for the most part, the vinyl came off in little strips, and left most of the glue residue behind, although some did peel off intact.There is still a fair bit left that I would like to remove, something like that sounds great.
