Well I bought my bike about a month and a half ago, and the tank protector was starting to peel off. I decided well that is almost defeating the purpose so the other day I peeled it off completely. The problem is it left some of the sticker behind. I managed to get rid of the actual 'sticky' stuff with goo-remover as I saw in another thread - however the sticker did not properly peel and there is hard, black plastic attached to my tank. Anyone have any ideas on what to use or experience on the matter?
