I think it is c possible that A M Philpot misunderstood you requirement, the work on reclaiming corroded fork legs, which have to plated and precision ground to dimensions, completely unnecessary on our spring boxes, what they did for me was a light polish to remove as much corrosion as is practically possible and then a very thin layer of hard chrome that should resist scoring damage. I have to say that I am very pleased with the results on my rear spring boxes.
