the more you take it apart, the better lookin your paint job will be(less likely for over spray or tape lines). hell alot of all overs we do at work, we leave the side glass in, just roll it down. u can leave the windsheild in just remove the trim(with the proper tool ;) ). if you take it some were to have it painted, if they don't have to take anyhting off, its usually cheaper. i can usually de trim a car(handles,panels, all outside stuff that isnt getting painted or taped up) in 3 hours.
