Try Island Girl Pink
If overspary is regular (singel part) paint yo will be able to reove it by carefully rubbing with some paper towel dabbed in a little IG pink.If it is two part LPU or gelcoat, there is no solvent you can use that will not also damage plastic windows (glass would be a different matter there you could use acetone).All you cna do then is to use some very fine metal polish or following with our CLLAR HORIZONS.You could use Meguir's platic polish also for this but there is much less abrasive content and may take longer. This also ahs a resin shine enhancer.ThanksJim WillisISLAND GIRL PRODUCTS
