Of course you can!
Several weeks ago I found myself on the receiving end of a minor rear-ender. It was icy, my brakes failed, and the gentleman behind me bumped into me. It was a low speed affair.
He cussed me out briefly while admitting my brake lights were on and turn signal engaged, then changed his tune and we got matters sorted out.
I got a few estimates and thought about getting the work done. I'll want to sell said vehicle someday and this sort of thing torques down the value. I let it go a few weeks as there was no hurry.
My husband decided recently that he could fix it for me so he made a quick trip to Canadian Tire for the materials, ordered the matching paint, and set about the work.
It's as good as done. All it needs is some clear coat protector which is on the way.
I am grateful for a number of things. It was a minor accident from which all parties drove away, damage was minimal and cheap to fix ourselves, and my husband cared enough to do it and to do a darned fine job of it.
Two things you may want answered:
The border around the license plate was put on upside down at the dealership when I got the car eight years ago. My husband put it on properly when he put the plate back on the other day.
The vanity plate is because I was a reporter for 20 years.
