Hi,
I would like to restore the engine compartment of my '77 Cadillac. I am trying to find out what the blue coating is on some of the bolts found on the rad support and fenders (not engine bolts).
I am told the blue coating denotes a metric bolt but no one seems to know what the coating is.
Thanks, Shayne.
