I did mine by masking tape around the area which should be bare metal, Xacto around the inner edges for a clean edge, then Acetone on a Q-tip & gently work the paint off, then carefully remove the tape. Blue or Frog tape works best.
These other sanding, scotch brite wheels & more aggressive methods could wear down the stampings too much, as they are often pretty weak stampings anyway.
Good techniques, but be really careful with the MEK(acetone). Even in small quantities it's explosive and carcinogenic. Along with benzene and formaldhyde, liberal use of acetone caused me many years ago to run away from being a QC chemist. They were the tools of the trade in the late '60's.
I used to keep a small amount around for detailing purposes on the 914 because it was so good at removing minor (an major) filth and grease. One time, I was dipping q-tips into the MEK and cleaning minor gunk from the injectors. Nudged a nearby screwdriver, which hit the cooling fan and apparently made a micro spark. FOOM! All the spent q-tpis went up. Fortunately, I had my halon extinguisher close by. Never used it again!
Be very careful with this stuff!
