If using 2 pack you will need an etch primer to begin. Then one of the following:

Solid colour with hardner added,
or
Metallic colour without hardnerr followed by clear with hardner.

You dont need an oven, just a decent mask, spray gun and compressor. You can buy faster hardner for outdoor spraying.

I would say that clear is more likely to yellow with the heat so if you go a solid colour it might be better. However, metallic gun-metal grey would look pretty nice.
