I had a similar issue recently after getting a small door ding in a parking lot. When choosing a shop I focused on finding a clear process where they explain whether original paint can be saved. A good approach for minor hail damage or bumps is Paintless Dent Repair since technicians work from the inside out using special tools. It avoids body fillers or sanding and keeps the factory finish intact. You can check link to see how the technique works and what damage fits this method. It usually ends up faster and more cost effective than standard bodywork if the paint is not cracked.
