Zinc anode sacrificial plates GQ

[SamIam]

Yeah thanks fellas, prompt and good answers. I will take a look at erps

My thinking is that the old girl has spent most of her life the other side of the range where a corrugated Iron roof lasts 120 years or more and is relatively rust free for her age.

Took her to Fraser a couple of weeks ago and plan to do a good bit of beach driving. While I can and do wash the underside as best as a hose can do I don't believe I get the salt off or out of all the nooks and crannies. It was suggested to me by a truck mechanic out west who has done a lot of work for me on the GQ in the past.

So Trukus; wots the downside of using zinc anode "buttons" at $5 a pop? Yes there is work in it, I have to find or drill a (usually) non visible bolt in every panel/part, rub the spot it goes in back to bare metal and bolt on the button... I have to do this in every panel/part that is (or might be by way of grease or seal) electrically isolated from the rest eg the bonnet. But otherwise there is no adverse reaction or chemical reaction when not submerged in salt water? Yes it is arguably over-engineered but on the other hand it will remove any inhibition to driving lower down the beach where the washouts from creeks are less dangerous...
