I recently did a detailed cleaning on my SP101 that I've had for about five years or so (this was not the first detailed cleaning). The cylinder face (or whatever you'd call the part of the cylinder that points towards the bad guy) has been "stained" black ever since I began to shoot it and no matter how hard I would scrub with patches and toothbrushes the soot wouldn't come off. So during this last cleaning I happened to have an old brillo pad in arms reach and was able to get the nice stainless steel shine to come back and the soot is gone.
My question is: will prolonged scrubbing of the cylinder "face" result in a widened gap between the forcing cone and cylinder? IF SO, then would there be a considerable pressure/velocity loss?
