No reason to apply stripper once you sand papered them. Thorough cleaning between grits and w the polishing ball. Wear ear pro. You're young so you won't heed this advice and at the same time need to start wearing ear pro now before it's too late. Why o why did you not clean the barrels and reverse side of the faces??? All that work just too be overpowered by the grime 8[ It'll be visible when mounted, js. Gud job w the rest tho.
