A buddy got a new windshield for his vintage ride and has tried endlessly to get whatever it is off. It almost appears as a fine overspray of paint; no way this coulda happened as windshield was put in after painting. Tried all sorts of cleaners, razor blades, even lacquer thinner. No luck. Thought I had read a post while back on something like this; but couldn't find it. Anyone run into something like this? Thanks!
