This is part of a three part kit I use from Dr. Beasley. Bugs and road tar melt off before my eyes, but without knowing what the scuff is, I can't say it would work for the OP.

And before anyone comments on the price, if $35 is too much to take care of a bike that cost anywhere from $16K to $24K new, you think differently than I do.
