Very mice B30 there. Keep the resto to a minimum & retain that excellent patina.
This was a question I was going to ask. I've seen so many wonderful restorations/re-paints, I just thought it was the thing to do. A friend that runs full size steam told me not to do much, just clean and repair. What is the standard procedure?
Empires are more often restored being they are so easy to color match and simple to restore. If you are undecided, keep it as is for now as it can always be restored in the future, but only original once.
A product many of us use is Ballistol, simply dry the engine down after a run and wipe it on. It can be ordered online as a spray bottle or aerosol, I prefer the first and pour a little on a rag. It will protect/feed the paint and keep away any future rust. I have also bought it at GunStop, their address is 14704 Excelsior Blvd, Minnetonka, MN 55345 (always test Ballistol before applying all over... had it remove some paint from an old accessory one time... other than that I love it)
As for polishing, I prefer Maas, cheap and available at many Wal-Marts and Ace Hardwares. It’s located by the mops and other cleaning supplies near the groceries at Wal-Mart.
