Mike Van Hove,

Mike,I'm no sure of anything right now cause I just got up,but I don't scrape any paint off that I know of in the break in process,just use lead pencil over the inside of knuckle & inside coupling area-maybe that is scraping off paint un be known  to me.(?) So far have noticed few problems. I know frustration,sometimes you just got to walk away from it all,at least I do until I can simmer down & collect what few brains I have left.

Hope this helps.
