I'm somewhat hesitant in wanting to blue a set of bbl's again as they always appear to be black and not the blueish black as on a Parker. Any ideas on how to achieve that blueish hue? I've tried solutions like M. Lee, Pilk... while finishing to 220 grit. Boiled to 180* carded w/0000, all oil free uncontaminated distilled. Would applying motor oil on a finished bbl. and then have it set out in the sun for a couble of months under glass give it a blueish look? Thanks in advance.
