I wonder if a good wax job after polishing would inhibit the oxidation on the aluminum, and thereby significantly reduce the polishing requirement?
There is actually a modern low maintenance solution.
They get a good mirror finish and then clear coat paint. No more oxidization. Done! I've seen it done on two birds now. a Cessna 195 that was absolutely stunning. Hurt your eyes to look at it! Even with sunglasses on! Other was a Globe Swift. Had more painted area (red) but the polished aluminum was unreal.
