Good points!
As mentioned I spray on a rag and wipe. Come to think of it, the breech seal is silicone, so silicone spray is probably a bad idea, afterall. It's still good for shining up the inside of a frisbee, though, for finger spins...
I've heard and read a bit about Non-detergent motor oil.
What should I look for on the label? Could someone post a link to an ND oil? I assume Synthetic Mobile One would be a detergent oil?
Thanks for the tip on storing in a case. Up until this year, I stored my guns in cases (Webley Tempest) or the original cardboard cartons (Sheridans). I havn't seen any rust on the Tempest, but will consider this standard advise to think about.
Thanks for the tips all.
