Underbody restoration / protection - Essex area?
Morning all,

Apologies if this has been asked but I have recently purchased a 2003 90 and I am looking for a specialist located in South East that can revive the chassis.

If anyone has any recommendations and a rough ballpark price i will be looking at for this service it would be much appreciated (i am Essex based)

Nick

Having used the services of Chris I fully endorse the work and high standards adopted……….. Bow down

I would have no hesitation in recommending him for defender underbody work, and protections / preventions.

Thanks for all the replies! It looks like the chassis has never been coated so it will need quite a bit of prep work before application. Just weighing up if I try and do this or get the professionals in !

Thanks again for the help

Having an older defender I can confirm that the chassis certainly can suffer from corrosion. Anyone you get to do this work needs to understand the land rover chassis and the signs of deterioration due to corrosion as there certain "hotspots" that suffer more than others.

Having just done a number of chassis repairs on my 90 I can point out some areas that have suffered in my own particular case.

Bulkhead outriggers. Mine had already been replaced in the past and I knew they needed doing, but until I started removing them I didn't appreciate how bad they were. These collect a lot of crud/water/salt being flicked up by the front wheels.

Rear crossmember. The construction has lots of places that create voids but more significantly places where two pieces of steel lap over each other. This lapping of steel holds the crud/water/salt as previously mentioned. If yours is in good condition then its really important to clean it out and let it dry before adding any corrosion prevention products. I have just replaced mine with a galvanised one. This had already been replaced before but was already well on the way to needing replacement so I bit the bullet and did the full job rather than patching.

Rear outriggers. One of mine had rotted at the bracket that joins to the tub. I also wanted to fit rock sliders and on trying the tube that slides into the outrigger tube on the vehicle, corrosion inside the tube was preventing it. I tried cleaning it out but to no avail as its difficult to get inside to clean and the rot in some places just meant it was easier to replace.

Also check the A frame crossmember (not sure if that is the correct name) at the ends where it sits on the chassis. This is another crud holding area so needs a good clean and then treating.

Don't be fooled by any advertising of a product that tells you that you can just spray it on and leave it. If you spray on to crud it ain't protecting the steel. The same goes with paint - if paint isn't fully adhered to the steel then it's just holding water between it and the steel and aiding corrosion! Also areas between brake pipes etc.

I did lots of the cleaning of my chassis on my back with a strong nylon brush and a wire brush (if you have a compressor and blow nozzle this is also really useful). You soon start to find the areas that hold the crud and you will also start to note where the corrosion is.

Deal with the corrosion where you can, but this is hard work involving wire brushes, grinders, etc. Be very cautious of the rust converters - my experience of these has not been good. For a rust converter to work you need just the tight amount of rust - not too much rust and not bare steel - god knows how you get just the right amount of rust when using a grinder! From my limited experience you do lots of hard work prepping the area, paint this stuff on (it goes a blue/black colour), paint over the top, then go back in 6 months and realise you wasted your time!

So, a quick summary.
1 - you need to establish the condition of your chassis. This is best done by giving it an up close and personal clean.
2 - deal with any corrosion issues.
3 - establish what corrosion prevention method you are going to use and apply it well.

Look at the corrosion prevention guide on this forum. You will see how important it is to have a good chassis condition before applying your dinitrol etc. Now ask yourself these questions;
If I pay someone to do this, how much is it going to cost?
When I give it to someone to do the work, do they understand the land rover chassis enough to be able to do a good job?
Do I trust the people I am giving my truck to to do a good job?

Note that people with a good reputation for doing this work will have your truck for a number of days to allow them to give it a thorough clean and let it dry before starting to apply the corrosion protection - and that is on vehicles in good nick!

By the way, just for reference, my 90 will be 30 in February so a bit older than yours.

Good luck with it. Remember to ask questions and use photos for people to reference so they can give better advice.

Thank you for taking the time to write such a detailed reply it's much appreciated. I am on the fence about getting someone else to do it as I do have trust issues Laughing that said on face value it looks like the chassis hasn't had any protection for quite a few years.

I think it best I get stuck in and have a thorough inspection / clean up to see what areas need attention and then look at my options. I wouldn't see any obvious issues following a quick clean but do need to spend a bit more time inspecting it

It looks like the rear crossmember has never been replaced which must be rare these days Laughing

Thanks again
Nick
