Speaking of painting out airline names:
In the 1970s - 80s, Continental Air Micronesia had a fleet of five 727-100 based in Guam, crewed by Continental pilots and local cabin crew and support. A pilot, freshly transitioned from the DC-9, pulled the power on short final to Truk, and wiped out the gear on the leading edge of the runway.
When Air Mike sent a crew to repair the plane, the govt of Truk said all wreckage belonged to them, just like all the war relics in the sea.
Air Mike sent a Guamanian mech to paint out their name and logo. He chewed some betel-nut, and then painted the golden tail into a sunfish...
