yes i know, you have a defender, you deal with it, oxidisation is the devil for all us defender owners..

on the new defender, its got a fair bit, whats my best option for getting rid of it, inside around a few nuts and bolts its bulbled up into like a slime, is there anything i can blast it with to neutralise it before i give it a good lick of paint, or anything i can clean it with to make sure theres as much residue gone before i do anything else?


cheers.
 
There are loads of threads on here if you search for them ... I use a product called Vactan which I find to be excellent. It is more of a rust inhibitor though ... Oxidisation is a little different! You can buy it on Fleabay. ;)

Oxidization is rust look up the meaning of it and you will understand what it means Everything oxidizes

"Oxidization is rust" Oh no it isnt - you look it up! Rust is Oxidization, not the other way round. Aluminium is inherently resistant to corrosion due to its having an immediate Aluminium Oxide forming on its surface, if scratched.

The Aluminium corrosion that is found on Land Rovers is, primarily, Galvanitic corrosion, which takes place when two different metals have contact with each other in the presence of an electrolyte such as water (mud) or similar.

This is compounded in the combination of galvanised steel and Aluminium. This is due to the fact that the Aluminium will be protected by the coating of zinc but when the zinc is used up the bare surface of steel can attack the Aluminium. For this reason the Aluminium should be combined with warm zinced material in an aggressive surrounding because warm galvanising, gives a harder coating of zinc, than hot-dipped. Galvanic corrosion can be prevented if certain steps are taken. One being by electric insulation between the metals, where the insulation has to interrupt the metallic contact completely.

I suggest you read TM-584C and http://www.calproject.org/pdf/CorrosionProtection.pdf

Yes thats what i've said use some rtv silicon between the 2 or in old days white lead paste to stop it. But everything oxidizes even your arse why you die
 
Rust just means oxidisation of iron - FeO - so i suppose if you're talking about something iron, then it follows that when you are talking about oxidisation, you are talking about rust, ergo in this context, fartwrapper is right!

Who cares!! Chassis and bulkhead rusts and body oxidises happens to all eventually!!
 
nope - tiz semantics, but he has the wurds arse about face - using my example, would you agree that "buses are vehicles" and "vehicles are buses" is the same? Of course not. Rust is Oxidisation, so is Aluminium Oxide, and Zinc Oxide, but Oxide (of Aluminium or Zinc) is blatantly not Rust, as rust is a generic term for FE03 (Fe+O2+H2O).
