Hi, I just removed the tank pad (protector) from the motorcycle because I don't want to have one anymore. Unfortunately the glue has colored the white paintjob a tiny little bit. I have completely removed all the remaining glue and the tank is very smooth to touch right now. How can I remove this very light yellow shade from the tank? I already tried soap, water, alkohol and polish - nothing helps. I fear that some solvents have penetrated into the paint and can't come out again. Thanks in advance, Lucas
