Or you can use Lanox (in an aerosol can). The idea is to not put too much on, and I'd assume the same with baby oil as all sorts of crap will them stick to the paintwork, so use a lint free rag to apply it also
This is the difference it makes (with Lanox at least)
Now Castrol has been repainted, I no longer need to do this of course, as I used the Protec paint
