...I took off my Z badges front and back and resprayed them satin black as they had faded from black when I bought them to a sort of brown colour (ebay cheapies).
Front one went back on no problem, back one, well at some point the badge had warped and was out of shape. I had lying around a 350Z badge in chrome, so I did a little spray job on that, removed the now knackered rear badge and put my 350Z on the back in its place.
Apologies for the poor light, but I think it has come out pretty well I had to use the sides of the 0 to cover the holes, so maybe it is a few mm out and slightly to the left but I think it works ok.
