I will give that a shot! Never thought about using it for that.  I hate working on greasy stuff. The rear shock must have been blown for a bit, as the oil from it was on everything, then dirt buildup over that. Combined with a carb that leaks a little and more dirt and grime......well you get the picture.  It is nice to be seeing paint again.  I want it to be as clean as possible before sandblasting.  Makes their job easier and the powder coat guys are much happier as well.
