I rented some baker's rack scaffolding last fall for when I waxed mine. Prior to waxing, while polishing/correcting it, I only used a ladder and literally almost died (suicide) as it took approximately 30 hours of polishing to remove scratches and swirls in the paint.
Having already had one major hip surgery and expecting another on the opposite side, I was down for about a week all but unable to walk.
Baker's scaffolding on wheels allowed me to do 10' swaths and I was able to do to eye-level on the ground and everything above that on the scaffold. Waxing took about 8 hours, between two days!
