Window tinting

Hey Everyone, I recently started tinting windows and lined up a brand new truck from the dodge dealership here in Port Elgin. Here I am thinking I can tint windows with the best of them, boy was I wrong! A little while ago there was a fella in my shop tinting a corvette so he tought me some techniques and set me up with a supplier. I used the techniques he gave me and did some used trucks and a few F-150s, then when it came time to do a dodge ram I used the same techniques. I wasted A LOT of window film trying to get it done perfectly because it was my first one for a new client. Finally finsished up I phoned the sales manager to come pick it up and after he did I received a call that the windows were scratched up a lot. I dove into the problem and it turns out I was using the wrong type of blade in my knife. I was using carbon steel blades and I should have been using stainless steel instead. Anyway lesson learned I supose. I still have some learning to do and I am very hopeful that the dealership is willing to give me a second chance! Thanks for the read!
