I read about the paintless dent removal... but that really applies to dents. What I have are door dings. Door dings are too small for dent removal tools.Dry or cure? It should be dry when you get it back. You should normally wait at least 2 or 3 months before waxing so the paint can cure. Ask the shop. If they bake it, maybe sooner.
BTW, have you ever tried paintless dent removal? It works great where there is no break in the paint. They've done some amazing work for me.
What size door dings are we talking about?? The doors dings I have are about less than an inch in height and about half an inch in width. Plus the paint from the other vehicle who hit my door, is left partially left on the ding. So either way if I had the door ding removed, i'd still have a little paint mark. I had about 5 to 6 dings on both sides of the vehicle through the course of a few years.That's odd; I've had them remove door dings and it worked just fine. The only issue I've had is that they cannot remove dents and dings that are close to the edge of a pannel where their tools won't reach.
