I have NO doubt you can do it!! You're a lot like me....the more anyone says that I can't do something the more I'm hell bent on doing it, even if it's impossible!!
The problem with cutting laminated (shaped/formed) front windshields, as opposed to flat glass, is the tremendous amount of stress that the glass is under. As long as you're careful and go slow and do a little reading (or U tube watching) you'll do fine. My "personal" biggest obstacle is patience, I want to get it done and I tend to get in a hurry. I've learned over the years to slow down but it's really hard after decades of working as hard and as fast I can. The only reason my body is so damaged (injuries) is because I don't know when to quit (and I'm over 60 years old!!!).
