Why not just use carpaint spraycans and masking tape. Yes the cans are somewhat expensive, but it'll look much nicer.
1:Clean it with alcohol or thinner.
2:Primer Layer. (http://www.euroscooters.nl/images/motip_primer.jpg)
3:Basecoat twice (black i guess)
4:Add white accents by masking the black with maskingtape http://www.wcmcape.co.za/wp-content/...2012/10/68.gif (wait 24h though, or you might pull paint off with tape)
5:Finish with clearcoat if you desire glossy finish.
