Hi all, At work yesterday some tard was respraying one of the industrial units on our estate a new lovely shade of green (it was particularly windy where i work yesterday) and alot of the spray particles seemed to have been carried across the estate by the wind and covered most of the cars (about 20!) completely in our park car with thousands and thousands of little speckles of green paint! I wasn't impressed nor was the bloke with the brand new Jag XJ!! They have said they are going to get the cars properly valeted come monday, so we'll see what happened when they comes back see how they look, else he is gonna get alot of bills for resprays!! But i really want to get the paintwork off the glass work asap, any recommendations on what i should use or it is just a matter of attacking it with white spirit? Cheers - Geoff
