Was cleaning a sunroof frame with every adhesive removal option you can imagine until, after hours of labor, I was done. Called my broheim for some advice and he went through the typical rhetoric of acetone, goo gone, et al. After he was certain I'd tried all that, he told me to buy this rather absurdly expensive (about $45) gum rubber adhesive remover wheel. To be short, it was worth EVERY penny and can be used many times. You are welcome.
