Boring paint- ideas please

Thats all preference as far as flat or gloss, but from there it will depend on the tools you have available. If you have a small detail gun, then you could buy a quart of automotive paint. Scuff, clean, mask, spray! Stripe it with a thin vinyl pinstripe to cover your paint edges, and wah lah!
If you don't have any tools to do it that way, and don't have the cash, then I would start searching for opinions on rattle can paints. Choose one that seems to hold up. However, keep in mind that with your location, the paint from a rattle can may fade fairly quickly. If you protect it correctly, even spray paint will hold up for a good while. If it fades in 2 years, whats another 20.00 in spray paint and a few scrub pads to do it all over again?
