After I was happy with the area I wanted to add some protection to repel dirt and water, usually I would use a good sealant and wax by hand but in this case due to hard to reach areas I chose a quick spray sealant. Spray on and rinse off.
A quick test to show it works...
Dried the area thoroughly with cloths and a air dryer to ensure no moisture is left behind.
Hopefully should give a few months protection and will work on the area some more in warmer weather. I treated the underside of the hood, used some metal polish on the aluminium areas and treated the spare tyre with megs tyre gel-this is important as the rubber will crack if left untreated over the years. 303 aerospace protection added to plastics and rubbers.
