I was replacing the entire steel floor. The new floor/wheel tubs were primed and the old bedsides had paint/primer on them from original assembly. All metal surfaces that meet had either paint or primer on them and I applied the strip caulk to create a barrier to keep moisture out. I'm doing close to a full restoration on my truck. My original floor was 99% rust free, but 46 years of use had the floor in a wavy and dinged up condition. I didn't want to replace the floor, but was concerned that the bed of the truck with the old floor would not be up to the standards of the rest of the truck. When I reach the point of the bed going back on the frame, I am going to sell the old floor, cross sills/supports, rear pan and wheel tubs on the parts board.
