chrome spray is more like silver spray, they chrome the cap, but the paint never turns out like that, just bright silver hehe
it will reflect though in sunny conditions and i wouldnt advise painting alot of the interior areas that get light on them. painting the gauge shroud would be ok because the chances of light hitting and reflect into eyes would be very minimal.
ive painted my interior white, well just the main dash insert around the speedo and also where the 4 vents are (that piece of plastic) with plastic primer and spray paint. ive had it on for about 8 months and havent lost any paint, ive also only cleaned it like twice and its white to, rarely gets dirty at all. i did not paint it in gloss, but a matt finish, its turned out quite well

if u want to see what the white parts on my dash look like, go to the teamnse site and theres ride of the month, should be a few pics of the interior.
After painting the interior, id go using vinyl spray it adheres to plastic better and is pretty much specially formulated for the stuff. its just a bit more expensive, but holds alot more paint/dye.
ie $13 bucks each for vinyl, vs like around 7-8 dollars each for good spray paint.
