That car is a guys of svag, met him when I got a radiator of him when I first got my Mk3. really nice car that, kind of inspired mine a wee bit. I definately know those light centres are done using glass paint. Also when painting the black on its best to use a cotton bud and dab it on as trying to brush it on doesn't work too well. I'd be tempted to use the sponge method with the black too.
