correct to a point, eventually it will wear down to a polished and correct fit which is the long way of doing what I do on a polishing wheel. When my sear engagements are taken to a high polish you don't need anything and they would take millions of rounds to wear out. Brownells does sell a semi permanent dry lube for actions, I can't recall the name but I bought some but have yet to try it out. It leaves a dry hard slick film that will only come off with alot of wear or harsh chemicals. I haven't really seen a need for it on my SA's since I polish the sears to a mirror finish anyways. I'm of the school of thought that wear on a factory sear is a good thing since it means the parts will wear together creating a better fit but I've not seen any gain in function from oiling an action. It's like having a crankshaft with a bad journal, you can put new bearings in and even though it's lubricated constanly it's just going to wear out the bearing anyways until that journal is polished, unfortunately unlike a sear though it will eat it's mating surface instead of wearing itself smooth.

The stp will work fine on the ratchet and gas ring though.
