Can anyone recommend a suitable product for spraying on the underside of the car to give better protection against winter salt and other nasties. In particular I want to minimise the corrosion on the aluminium hubs, suspension arms etc. I have in mind something that can be applied once a month or so, and then cleaned off in the spring.
Similarly, I am looking for suggestions on what to use to clean these parts when they get the black blotches on them.
Many thanks.
