I`m in the process of cleaning and inspecting the underside of my S1, apart from the usual muck and grime there are one or two surface spots of rust on the spare wheel housing, whats the best method of treating these without going to the expense and detracting from originality of spraying/painting the underside completely?
Also what do you use for bringing the alu/metal objects back to life? Ive started with the autoglym metal polish but its only a small tube and doesnt look like it will last long..
I`m no going for a show winner but I want to keep it as clean and as standard as possible.
