Here's the product I use for all corrosion problems. Have been using this since 1993, my outboard motor looks brand new under the cover.
I spray it on everything I want protection on. What sold me was in 1992 I went to a boat show and saw this 13" color tv turned on under water in a large tank. I couldn't believe what I was seeing. Talked to the guys there, took some home and have been using it since. It's a little pricy, but you get what you pay for, do you want the best protection you can get?
I have found it for $16 to $18 a can, I use the large spray can, last time I had to buy some, depending on where you get it. Might find a better price on line, haven't looked yet.
