I know this has been discussed ad nauseam on the internet but after much research I'm still not sure that i'm clear on a proper protocol here. I would like to bury some of my guns during the hurricane season so that if I have to bug out again there's less I have to haul with me. I need something that's water tight in case there's storm surge. The best I've come up with so far is creating burial tubes using 6" PVC and caps. Still not clear if I should fill them with synthetic motor oil or not. Some suggest greasing them up and putting them in vacuum sealed bags. Keep in mind this is Florida so it's a hot, humid, and damp environment. Thoughts?
