How does Magnaport do their pinstriping?

I've always liked the look of the vertical polished bands Magnaport puts on revolver cylinders and barrels and would like to try my hand at it.

How do they polish the metal with such precision so that the lines between polished and unpolished appear crisp and stright?

Anyone have any ideas?

Swag: They high polish the cylinder, then tape off the area they want to stay polished. Finish up with bead blasting the exposed (un-taped) cylinder.

Maybe...

I don't suppose they'd tell me if I asked, huh?

I'm wondering what they use that resists the bead blasting that well. I suspect it's some sort of coating that is washed off.

Of course there's electrical tape

and the ever persistent duck tape. ;-)

Vynyl Electoral tape works quite well for bead / sand blast making.
However, I doubt they take the time to trim it to size for those little straight lines.

On the other-hand, vinyl Chart Tape is already straight, and comes in many widths & colors! Take your pick!
