I think you can save a little money by buying bulk in sizes specific to the panel you want to ppf. I don't believe all panels require a 60" width. For example, you can buy 36" width bulk for the doors. When I did my model 3 I bought 12" bulk and cut it to 6" for the pillar above the windows. I bought most of my bulk film from Servoppf. Unless you have a lot of experience, I would recommend paying someone to do the bumpers and you can do the relatively flat panels like the hood, pillars and doors yourself.
