Gerry, No Problem.... I attached an MS Word Doc with the colors and steps I used to weather the walls.
It's the Second formula in the document, the 1st is what I did for Aging Concrete retaining walls. Figured out last year, if I didn't start writing this stuff down, I would forget all the steps and colors and not be able to repeat it in the future. Some more photos of the walls attached. I started with a medium or light gray automotive flat primer, didn't photograph that step, but the photos should help you see the process evolve.
