Restoring a Cub's Plastics- help needed

[Twilight]

I recently picked up a Honda Cub EZ90, is there anyway to get the yellowing out of the plastics or the scuffs? Its a textured plastic, but at a last resort i will sand. Heres some pics of the body.

Also there is sticker residue on the front... any way to get that crap off? Used to use windex, but if theres a better way do tell!

if minor,you can use a rubbing compound,there is a thread on it.really good results.goo gone works and so does gas for sticker residue

Goo Gone should take the sticker residue off.
