View Full Version : Stainless steel hooks

I have recently brought a 3.9 mtr tinny - and I put a false floor in it myself.

When I went to Nuts and Bolts to buy some screws - the guy there said that not many people are aware that stainless steel and aluminium alloy do not mix? - well this is a new one on me but he looked up some kind of book and it definately indicates that stainless steel screws and bolts will corrode aluminium over a period of time - looks like it's not only sinkers to watch out for but also stainless hooks

you can use something like a rubber washer either side of the aluminium to prevent the dissimilar metals touching. You can also use nickel paint which will also do the trick.

Or you can buy a glass boat or for the poli lovers a plastic one

sorry my son typed that ;D
one thing you can buy that "Inhibits electrolytic corrosion between dissimilar metals" (typed that off the tube) is some stuff called Duralac
cost anywhere from $25 -$35 for a tube but well worth the peace of mind :D
