Removed hinges, deburred, buffed w/ scotchbrite, cleaned w/ acetone, primed with Napa 7220 self-etching primer, then painted with Rustoleum Engine Enamel (good to 500 deg) per Steps 1-5 at Sect 45-18. Re-attached w/ clecos in every other hole enabling mach c'sink from flush rivets. Riveted, then repeated for other holes. Only done with aft hinges on Top Cowl, but making progress.
