Protecting Inside the Chassis Rails

My thread in Projects and Tutorials.
"130 Dual Cab for me"
Page 5 explains how I coated the inside if my chassis.
Whatever your choice if coating, the set up worked well.

I'm planning on giving everything a good squirt with low strength phosphoric acid (rust converter) but I'm not sure what do to next. What's the best way to protect the inside of the rails? I've heard fishoil and ATF Fluid but they sound messy. Is there a clean, easy product designed for this?

use waxol hose pipe pin holes all spray with good pressure first send a rotary wire head and then high pressure air hose jim

I wonder if you could use expander foam in the chassis??

It would definitely seal the inside well.

Would it cause any problems though? forget about ever looking inside and running cables in there.

WHY... don't JLR just fit (and charge for!) a galvanised chassis from the get go!!! :angrylock:

Actually, IF production continues ex UK after the December shut-down, the new 'maker' could charge a premium and make a fortune if they built the Defender on a galvanised chassis!!! :>)
