Funny because what Jon refers to as "cloudy" seem to be a common thing with the better quality KO's. I don't know what makes them that way but those baits never have any seam lines to sand, dents or other defects. They are excellent castings that don't need any prep work other that a couple of swipes with sone fine steel wool. They fish well and track true.
Mark, I tried your acetone prep several months ago, It works fine except I can't be around those fumes or odors
