The Creation Of A Spit6

Spitfire
First off, not all of us have a big garage with a lift, so getting the car body up for repair can be a challenge. We don't want to bend the car in half. Leaving it on the frame is the best for replacing the sills under the doors, that would be my first move, if they need replacing.
After all work in that area was done, I needed to get some paint on the bottom of the car, so here is what I did. You must use lots of jack stands, raising them a little at the time.
The boards are on the welded seam on the bottom, and 2 by 4, the large one I used had a tendency to get sideways. Brace the front and rear also. This let me get the firewall sanded in stages, as there are lots of things to catch you fingers, so taking time will save lots of cuts and broken finger nails. Plus here is where the rattle can of primer is a big time advantage, kind of a primer and protect as you have enough for the day.
At the end you will sand and seal it all before painting.
