So I was trying to clean the 47 years worth of hardened oily grime inside my tail section out, in preparation for possibly reweighing the plane. I first tried Aero Cosmetics aircraft degreaser. This did nothing. So then I tried a rag dampened with mineral spirits. Wow that was stupid- no need to remind me. Along with the grime, It removed a couple of small patches of the yellow zinc chromate primer that gives corrosion protection. So should I: 1. try to reapply zinc chromate to those two bare aluminum patches I caused? The stuff is carcinogenic as hell. 2. Maybe recoat those patches with Corrosion X? The plane is due on it's 2 year interval to get retreated with Corrosion X anyway at annual this December. 3. Don't worry about it, if this is not a corrosion prone area?
