Thanks Tim. Yes, airbrush on most things. I resisted buying one for years but there's only so much you can do with rattle-can enamels and paint brushing. BTW, same brown on seats, dash and convertible boot but each oversprayed with various matt and gloss clears to get different finishes.
Because of poor availability, high cost and 'corrosion' issues, I stopped using BMF a while back and now get by with kitchen foil (glued on with Elmer's Clear) and Molotow type chrome pen.
I didn't have a suitable coloured flock for the carpet so I used fine sieved sand which I hand painted after drying. At best it's ok, but don't look too close!
