hey, josh has a very nice idea friend!!
here is a couple of ideas that may be of interest, but you'll need some extra tools to do this with.
1. you could punch/cut out each instrument bezel decal and apply it in the appropriate bezel. it looks really nice.
2. OR, you could sand down the thickness of the instrument panel really thin, then, bore out the bezels with a drill/punch set. take a piece of sheet styrene and cut it into the shape of the IP. tack it to the back of the thinned down kit ip with some white glue or something easy to detach. spray the ip flat black as normal. when it is dry, detach the tacked down sheet styrene and you should have a nice polka dotted piece of sheet styrene in accordance with the kit ip. like josh says, take a sewing needle and a straight edge and "etch" your needles and tick marks onto the black polka dots. when you're happy, place a piece of transparency between the sheet styrene and kit ip for the "glass" effect, then glue the sheet styrene to the back of the kit ip. viola!! a scratchbuilt "PE" instrument panel!LOL i haven't tried it yet, but stole the idea from another forumer here who uses this method all the time. have fun. later.
