No not at the moment. But there are some steel plugs that show lots of rust and the floor cross brace channel is very badly corroded.

When you say corroded, is it serious depth corrosion or just surface rust. Others have said the same but when investigated it turned out to be suprficial surface rust.

I suspect deep pitting will ne the outcome. I havent had a go at it yet as I am repairing my spare wheel winch at the moment. The reason for going under there in the first place.

The dissapoontimg thing is that the Electro Plate coating hasnt doen its job too well. I would have thought that it would have been sound.

So I have cleaned it up. It looked a lot worse than it really is though the corrosion is widespread with lots of missing electro coating (paint).

What is the best method for preservation? I am thinking redoxide anti corrosion primer then hamerrite then waxoil.


Anyone else done it and what were the results.

Thanks

Take a look at this thread to compare what you found with what was under my 2009 when the body came off:

https://www.disco3.co.uk/forum/chassis-sus...65489.html

The car works quite hard, and the Dinitrol is still doing well, albeit after 8 months of this:



I found the worst of the rust was on the plating around the spare wheel depression on the body - the chassis was not too shabby at all.

It is much easier to apply if you warm it first - I sat the tub in a bowl of hot water before using it

60,000 dollar question

Is it better to clean up, zink prime and paint the rust then waxoil/dintrol. Or is it better to just clean up then waxoil/dintrol so that it can soak into the rust.

My preference would be the redoxide type approach then the waxoil/dintrol is the belt and braces inside the box sections

Sadly with rust nothing can stop it, but you can slow it down and I would be getting the worst off and chassis waxing it, not Waxoyl as its carp!

I wouldnโ€™t worry about the rust. The big expensive spinning thing in the front will go PT before the rust has done its stuff. Thumbs Up Thumbs Up

Bodsy used Corroless products when he protected the underbody of his vehicle and posted really nice pictures in this thread https://www.disco3.co.uk/forum/post1923653.html#1923653.

I have surface rust only on mine but have been โ€œresearchingโ€ what to put there to make it last. I donโ€™t anticipate a crank failure either (knock, knock) Thumbs Up

Well alll done, Maybe not the best but the best I can do. Scrubbed all the rust with a wite brush, chipping hammer and a chisel. Painted everything with zink primer. Hammerited the fuel tank protector, and finally because I have the equipment waxoiled everything too. Did some of the inside of the chassis with wax but didnt have the right bit for that so maybe come back to it..
