I have an 04 with a moderate amount of surface rust and it is going to get blasted with the dry ice method in a few weeks. I plan to remove some parts myself that are easy to do, so I can ensure the technician can get to as much of the underbody as they can. Remove step rails, spare tire (already removed), skid plate...I guess if you were going to do this to yours, and its a one-time thing, what else would you remove yourself? Thank you in advance, kindly.
