Should I have tipped?

About a week ago someone hit my brand new car in a parking lot. They scraped up the bumper a little…nothing too bad. I usually take my car to a local body shop that is good about giving discounts for non-insurance transactions. However, they were pretty booked up for a few weeks.

I found a new place that comes to your house for minor paint repairs. The estimate was about what I would expect to pay at my regular place. They did the work and did a good job. I paid with a credit card via a mobile scanner and was presented with tip options. I chose no tip. I wouldn’t tip a body shop or mechanic. Was I wrong?
