Best spray paint: Tamiya, dries like it's sprayed on
Honorable mention: Duplicolor, polishes real good
Worst spray paint: Plastikote, thick, smelly, and doesn't polish well at all!
Best brush paint: Humbrol enamels, dries smoothly
Honorable mention: Almost any Tamiya XF paints, they drive smoothly too.
Worst brush paint: X-18, don't know if it's going to dry glossy, flat, or maybe even semi gloss!
