I like the worn look because it tells the story of what the gun has been through. I just had mine cerakoted after 15 years because I was tired of surface rust.
I have zero rust on my SBEII, And I clean it with a water hose first pass. Here is what I do:
* I drop the action and trigger mechanize out. I used to breakdown the action down, but not any more. Drop both in zip lock bag with hoppes # 9, soak and shake, comes out sparkling clean.
* Rest of gun, high pressure water hose to start to get the big stuff off, hoppes # 9 in magazine and rest..
* Run snake thru barrel with hoppes # 9.
It will get a little oil, haven't put any on it yet.
