Don a metal disk and a t shirt or panties works fine and its under and facing the opasite way and if its reed it will collect on the reeds. I have my sideshot open on the kitted bike all year salt road dust
I get a whole year on a cylinder/ringer.
First ring is chrome and its a nikisal cylinder.
You would have to suck in something like quartz to even scratch it. And a chunk to fowl a ring on the cylinder ports.
