One thing you see is aircraft passing through mostly Aero Club machines not looking that flash. I mean yeah it's a club machine but hell don't know bout you I like a my Flying machine to look as good as it can when I go somewhere or even just pottering round the local patch.
So get off ya back side and don't wait to be asked to polish an Aircarft just do it as modern polish's it only takes 15 to 30 minutes to do a plane. Go buy some polish if there ain't any. I use Meguiar's Deep Crystal Wet Look awesome stuff. I can tell you now nothing stays on the wing slides right off. Bonus makes the plane fly faster and easier to get the bugs off.
Anyhoo here some pic's of the Mustang & 601 looking pretty darn reflectant.
