Rods, reels, line, lures, flashers...all cost a lot of money. As you are aware, the corrosion inherent with saltwater fishing can ruin gear at an amazingly fast rate. To help combat this issue, purchase a plastic spray bottle from your local hardware store for less than $10. Fill it with fresh water, store it in a cup holder on your boat and give your gear a quick spray wash-down as you change out gear and/or the end of the trip. After the spray-down, pat dry with a cloth and air dry. Washing down ASAP just takes seconds and absolutely works. Some spinners of mine have fished in the salt for 20+ years...clevises were bent and hooks were worn blunt from sharpening, but the effects of corrosion were nearly nonexistent by using this simple wash-down procedure in a religious fashion.
