some synthetic oils eat plastic especially when it gets cold out. i found that out the hard way with my bow quiver. hoppes #9 i believe has oil in it. bannana oil or something. i guess in a pinch it may work. id like to see some testing with these lubricant protectives maybe in the future.when i google long term rust inhibitors these seem to come up http://www.theruststore.com/Boeshiel...odnDUAdw%C2%A0 http://www.fluidfilmsalesusa.com/ff_maritime.htm
