I dunno, it sucked for me. I spent 2 days and 40 dollars on tint and tools and I ended up having to get it done anyways. I agree baked on is the way to go. The film thats most widely used by people doing it themselves is put on with water so you can slide it into position correctly which can be a mess. It's also difficult to cut it to be the right shape. I ended up getting it done mostly because of my rear window on my 89 legend. The curve on that window made tinting it well nearly impossible.
