Review on Efficient Plastic Razor Blades Scraper Tool For Scratch-Free Paint, Window, And Sticker Removal - 2 Pack With 100 Blades Kit by Robert Hole

I used this to get old paint protection film off a car that was cracking. I was nervous at first to use what is essentially a plastic razor blade on my paint but after the first pass there was no scratches or marring (and I used a lot of force). It almost was impossible to scratch the paint! Since they are plastic the blades wear out pretty quick but with the kit comes with 100 blades so.go crazy.
