I have a simple question which has turned out to not be so simple for me. I'm going on an extended 10-day kayak trip solely in salt water and am carrying my Pacific Salt, but I'm also carrying my NRS Pilot on my PFD. It is made of 420HC and is fairly corrosion resistant, but where I'm going there will be limited opportunity for fresh water rinsing as I have to carry all of my own fresh water. The question - is there a product that I can spray to stave off corrosion? Something like a dry lubricant gun oil, for example? Should I just take a tough cloth along and wipe down every evening? I'm not interested in any wet alternatives as the PFD was quite expensive and I'd rather not stain it with petroleum products. Its not the end of the world, but I would like to eliminate any rust issues if possible. I may buy the same knife in titanium, but I'm not sure that will fit the budget along with other gear upgrades.
