Ok all i can say is you gotta have a rotisserie to do a restoration. The elcheapo one I built will get it to a 45 degree angle and even that makes a ton of difference, taking it to 90 would make it even better but the difference would not even come close to the first 45 degrees of rotation!
This is a partial days work including taking my daughter to town at lunchtime. All I need to do is roll it the other way and get the other wheel well and the opposite sides of bumps and bulges. 2 days and we will have the under body stripped ready for sanding and epoxy primer. I won't even guess how many nights I laid on my back covered in dust and grime on the Coronet and this one is going to be done much better than the Coronet.... Sorry old girl....
Also being able to roll this thing outside to strip the undercoating, wire brush the rust and clean the garage is worth all $250 or so I have invested. It will also make fixing the trunk and quarter panels so much easier.
