Grinder sparks in rear window?
I just got my windows tinted in my BA ute that was a demo model when I bought it. Except when I got the tint put on, it has highlighted what looks to be sparks from a grinder (according to the tint guy). The tint guy said he normally sees this sort of thing in older cars where people have cut holes for new speakers with a grinder. Now I havent taken a grinder to my ute, and there is no evidence of a grinder being used in the cab so I am thinkin that it must have happened at the ford factory.
Any ideas how this could have happened? Do you think that I would be able to get the window replaced under warranty? Or am I up a certain creek?
