+1 for the vinyl. Spray the chassis and blanking plates etc and vinyl for the flat areas/graphics.
If you have the vinyl printed up first, get a paint shop to colour match an aerosol can of nitrocellulose to the blue of the vinyl.
I've had colour matched aerosol cans mixed up in the past for various projects, if the shop is any good the colour match is perfect. Here in the UK, there are a number of places that I have used, and they charge around £15 for a 500ml aerosol.
