As I get closer to one day actually taking delivery of my Model 3, I'm beginning to wonder about maintenance. How do other "northerners" care for their Teslas during these long and dirty winters? Does anyone take it to a car wash? (Can a Tesla safely even go through a car wash?) Also, coatings? What sort of "clear coats" are members using? Opti Coat Pro + gets a lot of promo on Tesla sites. Is it worth the cost? Any recommendations about where is the best place to get it done? Thanks!
