No knowledge in this area, looking for experienced advise. I had my Hot Heads headers ceramic coated, (misspelled above) and it appears that there are small specks of rust on them where they exit the heads. Piss poor work I know but I don't want to jerk them off and redo them. So the question: There are rust removing solvents I've seen on the shelves and used some at times in my life. Any one know if that stains and/or works to take it off??
