What about the powser used in Smoke Shot silencers?

I know that stuff ends up inside your inner barrel, I didn't notice any change in accuracy, it's light and comes off fairly easy, though it also gets everywhere fairly easy (just touch the outside of the silencer and look at your fingers), and it wipes off with a paper towel or just your other hand even. It seems kinda graphite-y (much like powered pencil "lead")... it wouldn't leave a huge mark to be sure, and you'd probably have to colour it to notice it...

But just an idea that popped into my head after reading the thread.

Edit: Personally, I too am good with the current honour system... it's what sets us apart from the kids who 'need' paint or other markers to display their hits.

I am much more at ease with a group of people I know are honest and honourable enough to call their own hits, rather than feel the need to display a kill to prove it. It also speaks volumes about the players in question that they can be mature enough to play this way.
