Thanks, yeah I am going to do all the badges that colour as I think they look good alongside the black bodywork. I am also going to colour code some other bits like the wheel centres and the like when I get some BBS' on it.
For the GTI badge, I degreased it for half hour. Washed it clean then primered it. Then added a coat of gloss black and baked it in the airing cupboard. When that was dry I masked it with 5mm masking tape and covered all black areas twice to make sure. Then painted the badge with the colour. Then baked again. Then added 2 coats of the lacquer and baked again.
Then left for day to dry out in the airing cupboard and peeled the masking off last night and with a bit of luck or skill no paint was left on the black at all...
