RIG
I have used RIG - since as long as I have been around.
I do TREAT bores with RIG , always have, still do and will continue to do so.
When I get new firearm, or actually clean the bore of one, I treat it with RIG. Now I don't get anal as folks do about cleaning bbls, I concern my with chambers. I do shoot in rain, get muddy, expose to snow,...etc.
I do what it takes to remedy whatever I have exposed the firearm to. I have had to separate the metal from wood...dissassembly...because for instance shooting in 30* F temps, with rain, sleet and snow during a tournament...everything gets soaked. I do mean everything.
A light film of RIG is all it takes. I do internals as well. I have used in 125* F with the Heat index...and -5* with the wind chill factor.
Under stocks, grips ...etc. as well.
Now what I discoverd by accident...and shared with CRSam...I needed to clean a gun and had no solvent ( like I said, I don't get wrapped around the axel about all this stuff). I applied RIG using a long Cotton applicator, swabbed bbl, let sit and we went to eat. We did stop and buy solvent while out. Didn't need it...could have saved money...
I used a Otis pull through on the revolver bbl...removed the RIG and all sorts of fouling came with it. I knew RIG "seeps under and into metal"...well by golly, I knew the stuff was good ( never had a problem with RIG) but this was incredible! I used nothing else, the bbl was clean . I treated bore like always , as I did the rest of the gun. It does not take much.
The RIG+P does this too. WE kept trying to tell ya...
