Bracing on tandem subframe

I got bracing done on tandem subframe, I cut a circle in some diamond plate to cover hole in coupler and I added topcaps to main gooseneck uprights, still need to cleanup forward tandem slide brackets. Will be reversing polarity on welder today to weld all overhead welds. Sherwin Williams is getting me my primer and paint, heavy duty industrial, I'm not spraying in my shop and getting unwanted paint and primer all over my equipment so I've specifically told them I need to roll it on...Looks like it will be a two part mix on paint. Information forthcoming...
