I like the way a good pressure washing looks, but I don't remember anything during my formal A&P training about pressure washing. I never read anything in the maintenance manual or the old AC 65-15 about pressure washing. I'm not judging, but I'm curious about tech data for cumulative fatigue on aluminum during a pressure wash....I'm sure it's dependent upon pressure, metal thickness, area, etc. Not to mention, that not all Skymasters are equal...pre 1973 used thinner aluminum. Looking for a discussion, not a shooting match.
