I've been giving the Defender a bit of a tidy up and fixing some of the things that should have been fixed a long time ago.

Then I started looking at the chassis and other associated "underneath things" and found more rust than I would have thought was there.

This is a 94 110 wagon that has done 115,000 k most of them hard off read ones. Plus where we are here in FNQ stuff rusts at an amazing rate so the problem has got worse over the last couple of years.

At this stage it is moderate pitting and a few seized up nuts. The RWC bloke reckons its not an issue for him YET.

What I want to do is arrest the rust process as well as make it look a bit better. There are any number of products around all claiming to be "the best"

Paints you can paint straight over 2 to 3 stage processes etc etc etc. The idea I liked particularly is paint over, looks like hammertone, and seals in the rust?????

Has anyone used any of these products, do they work and for how long. Guess I'm looking for the best result with the least amount of work. (aren't we all!!!)
Jokes aside ease of application is an issue, I don't want to spend the next month doing it.

rust expands as the steel is corroding...any surface treatments eg paint cracks, so the cycle keeps on going...you need to arrest it...grind it out, chemically treat it etc etc

1/3rd sump oil strained thru a chux and 2/3rds diesel . Put into a sprayer and spray under every now and again . Works for me .

I recently sold my 88 Troopy, but in the final 12 months of owning it I was able to significantly slow down the rust issues it had. Initially I mechanically removed as much as I could and treated some of the harder to get to bits with some of the chemical conversion products available. I then installed (cost of about $600) a Couplertec electronic rust prevention system (heavy duty with 4 pads). I have to say it was amazing how well it slowed down the rust process. I had rust in many seams around the roof and windows as well as floor pans and the Couplertec slowed the advance of rust almost to zero. Outstanding product and I highly recommend it. Dead easy to self install as well.

Needless to say I took it out when I sold the old Troopy and the unit is now in my 100 series Toyo. You can find more information at

Couplertec

....not affiliated just a satisfied customer etc etc.

Cheers & I hope your not too wet up there in FNQ !!

Submerse most of her in a dam with an appropriate concentration of washing soda in it, drop in an anode and run a current between anode and vehicle. 24 hours and your rust will be converted.

I used a chemical treatment on a fertiliser spreader and that stopped it. Super and other fertilizers are very corrosive and the rust hasn't continued since the treatment.
once the treatment was done I also put on a few coats of bitumous paint, created a barrier, under a car this would break down in time with stones flying everywhere.......

Somebody, somewhere, posted something on a product called something like "Lanotek".
Buggered if I can find it again, but apparently it's quite good.

Thanks for all those good suggestions, I even like the dam idea, if I had a Toyota I'd try it like a shot!!

I'm still interested to hear from anyone who has used a "paint over it" product such as POR 15 or KBS Rust Seal.

Ive used POR15 or somehing similar. They are ok ,but it needs to be checked and reapplied occasionally.
This will be the norm for all rust converters/protectors

Ive also used the Lanotec(a lanolin based product) with success.

Maybe try a couple of types applied to various sections and decide after 12 months.

Putting a sealant over the top could be heaven or hell because sometimes air/moisture can get under the sealant start the rust process off again

I used Selleys Rust Dissolver on the trailer, then painted it with Zinc Chromate paint.

It works best if you mechanically remove as much rust as you can before applying. I used a wire brush attachment on the 'ankle' grinder.
