My Doctor Who pinball was badly faded like all Doctor Who pinballs seem to be. The decals don't seem to be available and my solid-fill with glass paint doesn't work for colour gradients. I decided to try spray painting the cabinet. In an ideal world I'd have an air brush but this is not an ideal world so I made do with an aerosol spray paint can.
I am extremely impressed with the results and recommend it. It's simple enough to practice in a mock-up situation with a piece of board and some tape. If I were to do it again I would glass-paint the yellow first. My yellow had dried out and all the shops were closed so I couldn't/didn't do that. I'd mask the "DOCTOR" as well as the "streaks" and start button circle. I would also base-paint the "WHO" with an apropriate yellow before over-spraying with the red. Spray-paint is good! I only put on one coat and removed the masking tape within a minute or two of applying that one coat.
Another view. I sprayed from about 600mm away using a very fine drift spray. You end up with red spray powder everywhere but it helps make an even job. Practice with a piece of white paper covering the "WHO" to get a bit of practice.
Usual story, no garage/shed so lounge is it! What a tolerant wife! ;)
Note: The spray paint I used was:
Plasti-Kote, Projekt Paint, Gloss Super, 340g, "1120, Bright Red, Rouge vif, Hellrot"
The nozzle is fantastic on the can I have. I've had other branded cans and have had splutter but this one was excellent. It could just be the luck of the draw though.
Note: After a period of use I recommend using paint around the "Start" button (and anywhere that fingers will rub) as the glass paint "wears" with finger use.
There are heaps of high-resolution images of the finished cabinet here.
