ok, apologies if covered a million times..... basically, i use rem oil for all my gun oil needs. every finish i have (blued., stainless, parker...etc).....i use rem oil as my go-to for the final wipe down for protection. i think i use rem oil on my firearms so much because it is cheap and available everywhere. any down sides? is there something better to use for specific finishes? is there a better product out there for this purpose? thank you.
