Re: Blue Chromate?
Your VW bolts might have been dyed after chromating. Do you have photos of them? are they really a full blue color?
Most "blue" chromates are really clear with only a very slight blue tint, like the one in my photo. The degree of "blueness" depends on the particular chromate formulation.
There are hundreds of different blue-clear chromate formulations from dozens of different manufacturers, but Caswells is the only one available in small quantities (as far as I know), for reasonable cost.
