Sure. I was painting the TDC mark on the timing chain cover white. So I could see it better. Well I got a little paint run off. So I took a small paper towel, sprayed some break clean on it. To wipe the paint run off and just barely touched the Dampner. Needless to say that the timing marks from 30 to 40 degrees are now gone. I guess the timing marks on it are painted on and not machined
