I am in the process of prepping my cab for paint after I get rid of all the dings and put in a new rear lower panel on my 1948. I was wondering if there is clever system to roll the cab on it's back so I can clean up the bottom. I used my engine hoist to lift the cab off of the frame and it's sitting on a rolling cart that I made up so I could move it around the shop. I was thinking of just building up some lumber on the shop floor to the height of the cart and just rolling it back onto the lumber. NOt sure how much it weights. Since the rear lower panel will be replaced anyway, I won't mind if it gets scratched up. There are no rust holes in the floor, so it's solid. Just want to prime and paint it. Also any thoughts on putting on a protective coating on the bottom, like a bed liner or is that overkill?
