Well, the notch I just bought has this god-awful purple tint on the rear and rear-side windows. I can barely see out the back on a clear sunny day.
Sooo.... How the heck do I remove this crap without ruining my rear defroster. I think the tint shops use this bottle of stuff they spray as they pull it away. My question is, what's in that bottle that kills the adhesive? Is it just soapy water or vinger or something? Maybe a chemical?
As always, any advice is much appreciated.
