I waxed the shell with Autogym for protection - I figured that this might be easier while the car is still in pieces. It also might give a bit of protection from the masking tape I am about to put on around the front suspension area.

The powder coating on a little of the bottom of the frame was scuffed so I sanded it and painted it with Hammerite.

I also gave the engine bay a coat of Dimitrol to hopefully reduce the rate of corrosion; especially between the steel and aluminium joints.

If the Dimitrol looks Ok once dry, I may go and coat more of the underneath.
