Uhm. Sorry.. this is a dumb idea.

By the time you buy everything you need you're close to getting your windows tinted professionally with higher grade film then what you buy off of eBay.

I was with you, I thought I could do it. It looks easy. No matter how many videos you see, it all looks the same. Looks to be a 10 minute job.

You'll spend hours trying to perfect it and you'll still have bubbles. Window tinting is something you learn by experience, and you have to have done a lot of them for it to come out good.

I went through about 3 kits, my 3rd one was the best but it still wasn't perfect. I spent about $100 on the kits/materials, and I paid $150 to get them done professionally with 3M film and they look perfect.
