So I recently went abroad to London and took the IMI (Electric Vehicle) course. It's purpose is to properly and safely power down an EV car when performing paintless dent removal. It's much more dangerous than you would ever think. Also I mention why I use sharp tools especially for aluminum. If you are considering taking the IMI course, here's a link on how you can find more information. http://www.ansonpdr.com/training/level-2-ev-hybrid-qualification.html
