The last time I did it for a customer, it was 3 sliding glass door sets. I sprayed the glass with ammonia and water and then put a black plastic trash bag on the glass. The water and ammonia made the trash bag cling to the glass and the heat from the sun and ammonia loosened the tint so I was able to peel the majority off. The rest was done with a heat gun and a Triumph scraper. Very tedious and messy work.
