Sanded Brake Pedals, Forward Baggage Shelf and Side. Scuffed these as well as the Throttle Quadrant Mount and Cover with a Scotchbrite pad and them prepped them with Alodine. I will be switching to a Zinc-Chromate Primer that I found on SkyGeek.com after doing some reading. It should provide a better base coat for the aircraft grade paint than the automotive Dupli-color primer.
