I was talking to a co-worker of mine about buying a framing gun and turns out he used to own a contracting business until he got sick of riding herd on his crews and hung it up. He said he still had half a dozen nailers in his garage among other stuff and sold me a bostich stick 95rbh for $50. All it needs is an o ring rebuild cause it sat so long. My question on the o rings is do i need to use the o ring grease or can i use marvel mystery or other non detergent oil like the air gun oil i bought on them when replacing
