Your suggestion of Brasso was fantastic. The regulator was kinda messy(and cheap). Looks very nice now. It came with stock gauges with plastic covers, but those forged brass and glass Wikas are sweet looking.
What it looked like on eBay...
Im Plastidipping the knob and CO2 tank and its knob, red and white to match the Vertex equipment.
When I saw your brass one on the front page, I woulda swore that was out of my price range or budget.
It looked like $1000 worth of sexy shiney brass to me.
It came in less than that Carbon Doser regulator.
