I had engine/trans and all trim, bumpers, and wiring in addition all items off firewall and radiator, inner fenders plus glass removed. I reinstalled front clip, only the sheet metal and completed all body work/primer, block sand etc. to set all gaps and body lines in addition to trunk to tail pan etc. This way all surfaces are one level and uniform in gaps etc. Then pulled front clip off and made notes and assured all shims and bolts tagged/bagged to go back into same location to duplicate adjustments. Proceeded to "cut in" fenders ,door jams, trunk area and hood and front valance etc. Reassembled front clip keeping shims and bolts in order, adjusted back to previous gaps and body lines and finish. Taped off sub frame and all openings, and used 3m foam soft edge tape to create soft lines at all gaps in doors fenders, trunk etc. Painted car, wet sand buff. polish etc. No matter how much you tape off subframe, areas etc. all the over spray and wetsanding , buffing debris gets into nooks and crannies. This is why I left sub frame in and then removed control arms etc. to replace ball joints ,bushings , springs, shocks to have all the new parts FRESH and a cleaner look. Did same for rear suspension and trunk floor as it is easier to cover whole car with Blue shield plastic cling and not worry about all the detail painting overspray. Reinstalled engine/trans etc., wiring , brakes, glass trim etc. with detailed fresh and no overspray. Do as much as you can to save time and money and communicate what you want as a finale product. And when reassemble just everyone be careful and use protection. I am novice and have done it from start to finish so make sure no rush jobs and you will be happy.
