Stop throwing your rifle in the creek every time you catch a fish and they might not get so rusty. Until then who gives a fuuck about rust...
Oh no wait, my bad, you live in a rain forest must be all that hard chargin' in the rain........yeah right.
I should drag one of my rifles behind the pickup for for a mile or two down a gravel road and then take hero pics of the poor thing and all the 'hard use' its seen.........
