I have some surface corrosion on the front nearside wheelarch (trailing edge) and rear nearside wheelarch (leading edge). In the past I've prepared the surface and resprayed but it needs doing too regularly. What underbody/guard product can I use on the bodywork and then paint over with basecoat and lacquer?

I purchased a can of Motip Stone Chip Spray and it seems to have done the job well.

I use Ship Coatings Ovatrol.
