Next I decided to check for rust and tidy up the rear underside:

I removed the rear bumper, both rear wheels, the spare wheel and wheel holder. There was a fair amount of corrosion on the passenger side rear chassis leg but the rest of the car seemed in fair condition., helped by the fact it has been under sealed at some point.

I removed the fuel filler pipe to gain better access, then cleaned up the corroded chassis leg with a wire brush. I then rust treated the whole rear underside before sealing with silver Hammerite. I treated the rear arches in the same way and made sure to get into all those little rust traps. Next up I cleaned the rear beam, the spare wheel and holder and then coated all with Hammerite smooth black. Finally I checked the spare tyre pressure.

This weekend I plan to go under again and finish off/tidy up. when I get the funds together I will invest in a waxoyl sprayer as I intend to fill all the box sections and sills full of the stuff before winter.

After a quick wash down, a fair amount of rust was revealed:
