Hello All: Forgive any ineptitude as I've never been part of a Forum before. Two questions: (1) I have a couple small dings on my Model S (2015). Do I need to take it to a Tesla-approved shop, or can any shop work on the dents? (2) I live in the country, four very different seasons (New Jersey). No garage. Use a cover, or ignore? Smart MIT friend says all car paints are quite durable not to worry (he's also a builder, so would do well if I built a garage!). Also thinks effect on battery minimal. Thoughts? Thanks.
