Well I have a compressor and air gun so it's alot easier than rubbing down by hand, Just used different grades of sand/rubbing down paper, you should maybe consider getting the lips diamond cut.
A few snaps of my Cookie cutters when baught and during the rehurb... Staggered 6J and 7J When I had bought them... Paint stripped Polished lip... First one painted... Close up, painted in a dark grey with a slight metalic effect
