Helped a friend/student polish his gorgeous but a bit neglected C-172. We both thought "this won't take long". HAR.
After the first exhausting afternoon, he was headed to Sears to buy a big, soft buffer. We did the whole airplane both by hand and with the buffer, and it was STUNNING when it was done. It, too, had the one, classic stripe down the side, with a split stripe up the vertical fin.
It's still one of the prettiest airplanes I ever met. I wish I had a photo! He got compliments every single place he went. (On the airplane, I mean).
