I'm pretty sure the indulgence electroplated pot metal... probably not the best thing to have in your environment. I would say that an all stainless Mechanical mod is the way to go- like a Prodigy or icon. They both have switches that can be easily disassembled and cleaned without any tools. I bring my Prodigy V3 with me when I'm out on the water - I've dropped the damn thing in the fish cooler a few times. Only takes a couple minutes to clean up. I haven't noticed any corrosion either - then again, I'm pretty .... about keeping my mods clean.
