not sure where this should really go... but anyway


Anyone ever tried this? Its something i've been thinking about for some time now and there seems to be plenty of information on the subject. Only thing is, I’ve never seen it actually applied in our application – i.e. on a car?

I might be wrong, but there seems to be two possible approaches? One is to use a voltage, possibly from a battery or similar lowish voltage source (I think 1-2v or something near there is needed, 0.7v for iron???), to prevent the chemical reaction? The other is to use a sacrificial anode in electrical contact with the body, so maybe a block of zinc bolted to the boot floor for example???

Thoughts? I maybe getting the wrong end of the stick, which is why its possibly not been used properly before!

I've seen the future and tbh its Pie

Cathodic protection is only needed where large currents already flow, usually induced by things such as DC railways. That is, the cathodic protection is there to stop any current that flows by putting a voltage in the negative sense to that being set up erroneously.

Does that make sense?

So, basically, it wont work.

I think its a case of in air not enough current flows to have an effect , in water Especialy salt water it does.

Joe, do you have a photo of your tool?

We use sacraficial anodes to protect steel subsea structures and pipelines and hence there is a vast amount of electrolite through which the current can flow (ie sea water).
The zinc of the anode is essentially eaten away instead of the steel.

I looked into zinc based primers during my rebuild, and I think the zingerfroug is about 80% zinc, and a layer of this is a close to glavernising as you can get, with out actually doing it IMO.

All the top car manufactures that don't have corrsion issues galvanise there bodies.... My honda is nearly 10 and has no corrision on the body and I live in scotland, so it gets covered in salty water every winter.

Worth thinking about...

Wax oill is a must for all the internal open seams also.

BTW - I took my buddy VTEC Pete out for a spin this weekend, and even though I am running her in, he gave it a name, the "Brocket"...cause I'm a brocket maaannn, nah nah nah nah nah nah nah nah nah nah nah....
