For an hour and a half driving in 1/4 mile visibility on an ice/snow highway, damage seems rather likely. However, my damage didn't occur until I was backing up into my driveway - naturally my backup camera was blurry at the time - and I backed into a darn handrail. Now I've got a ding at the bottom right side of my tailgate.
How do I go about fixing it and making it look shiny and new again?
Note: Simple explanations please - I am not very savvy with vehicles, though have been learning. This thread concerns me but would a touchup pen be a good match for the fix?
