Is there any easy way of doing this? Recently purchased a set of used facelift rear lights, I noticed the driverside one has specs of overspray on it. I've tried to use SRP and Tar remover to see if they would have any effect, but no use. I don't really want to try spirits on it for fear of damaging the surface as it's plastic. Anyone have any ideas? I don't have a machine polisher to hand to give that a try unfortunately.
