Hey, I just had a fender bender on my car and noticed another scratch on my side. I wanted to fix this at home but was unsure how to go about it. Using touch up paint seems like the best idea for the back but was wondering how to get the transferred paint from the other car off? Also if anyone knows what to do about the scratch on my last picture, if I need putty or just paint for it, would be much appreciated. Thank you!
