Thanks for that Beans...
..... yes, the car will be going to the bodyshop to be repaired/ painted but in order to make the job as easy for the repair guy as possible I will be stripping the car myself. The reason for the body spit is so I can do the entire underside of the car myself - clean, treat and paint and underseal, which I think will be easier if I don't have to work upside down under the car.
The floor has no rust perforation just muck and a few rust scabs.
The car is in great condition but almost every panel has a defect of some description, a chip or scuff or ding, so it will need repainting. I was just worried if I leave the windscreen on is it likely to crack with the stress of being on the jig and also will the jig cope with the extra weight if the doors are left on.The car as it is at present.
