There seem to be a couple of active threads about underbody restorations so thought I would post mine which is currently ongoing.
I bought my L322 back in Febraury and although not initially keen on the colour it has grown on me. I bought it because it has relatively low miles at circa 100k but has been serviced every year regardless of mileage.
Bodywork was in pretty good shape and only slight corrosion on the rear arches which I got a body shop to repair and to also repaint the rear bumper.
Underneath there was some surface corrosion on the subframes so I have stripped and repainted those but I didnt take any pictures of the process.
I could some corrosion around the jacking points so decided to investigate further.
there was a decent amount of mud in the sill covers!

I also removed the heat shields and the fuel tank guards which contained a huge amount of mud!

The jacking points werent too bad with only surface rust but there was more surface rust under the arch liners and fuel tank guards

I ground back the flakey and bubby bits mainly with a wire wheel. Compressed air line came in very handy to blow the remenants away. I then treated it with rust converter and have last night painted it with...

I had the paint tinted in something vaguely similar to the body colour but as you can see it isnt a perfect match but it will be hidden under the car or behind plastic covers. tonight I am spraying it all with Bilthamber Dynax-uc
