And you'll only learn if you do it yourself! When I got my first Blitz ER34 (the Speed Way Pal version), it looked like total butt. And it's sad cuz I've been painting RC bodies for quite a while. But at the same time, I've been experimenting with paint. From there, I learned about custom blending, and started using different paints. Here are some examples!
Speed Way Pal ER34 Skyline. Pactra White Pearl, Candy Blue, Silver
Speed Way Pal AE86 Trueno. Spaz Stix Blue-Purple-Red
Yokomo HKS S15 Silvia
HPI Impreza WRX STi (My crappiest job to date)
HPI FD3S RX-7 (My best accidental paint mixture. I call it Candy Grapefruit)
Yokomo Blitz ER34 Skyline
Yokomo AE86 Trueno
Tamiya HKS Altezza
Hot Works Nismo Z33 Fairlady Z S-Tune
The S-Tune is my one and only pre-painted body. everything else was pretty much trial and error with the paint mixtures. I've used Pactra, FasKolor, Tamiya, Spaz Stix, AlcladII, and House Of Kolor paints...
Hope you all enjoy!
