Don’t let them wash it, they will swirl up your paint pretty good. If that sort of thing doesn’t bother you then I guess it doesn’t matter, but to me it does, I do detailing on the side and I did not let them touch one thing. Drove it home with all the plastic on the seats and whatnot. I will spend 2 1/2 to 3 full days doing a complete detail and ceramic coating myself, and the less swirls I have to buff out the better.So I’m about a week away from getting my diesel. Any suggestions or pointers. Dealer wash or no wash. Anything at all let me know. Thanks.
