I’ve done something as large as a quarter before and was pleasantly surprised with the results, you can really hide some nasty bruises…but it sounds like a shop will be taking care of this car.
Also, it doesn’t require anything more than some wetsand paper, compound, glaze, and wax…everything that can be found at Autozone/Advance/etc. This isn’t a high-tech operation since it can all be done by hand.
