If you are talking about wheel bore polish #2 then you can go out and buy and use LiquidGlass from an Automotive store. It is not as fast as DD4H #2 or Red Rocket, but it should do just fine for a scout type race.
If you are talking about axle polish then you can use Brasso... one again not as good as DD4H axle poilish, but will work in a pinch.
