I used t-cut on my car to bring back the shine again a while ago but parts of the ridges on the roof have worn down enough to show the white primer underneath. I was thinking rather than attempting to touch these up with spray paint (and muck it up), I could just clean up the paintwork with meths in that area, stick on some of those stripe things the entire length of the roof, then slap some wax on. This is the sort of stuff I'm thinking of... Pinstripe 12mm Black from Halfords Price £3.49

I was wondering if anyone had any experience of using this sort of stuff and what the results were like?

Erm...

Well I guess you could just get the whole roof covered in white vinyl?
