Polished the wing skin surrounding both fuel tank fill caps in preparation for applying the fuel placards. I used a 4 step process I'm finally settling on which includes 1. Sanding/scouring off stains/corrosion spots, 2. Three passes with Nuvite II grade F, 3. Three passes with Nuvite II grade C, and 4. Two passes with Nuvite II grade S, once with a cutting pad and once with a random orbiter buffer and a micofiber cloth. Shines up really well.
After completing the polishing, I applied the 100 Low Lead and fuel capacity placards.
