I think the metal chassis might be powder coated. I have a wear mark or chip in the corner from someone else not being very careful when she put it back in the aluminum briefcase. (My wife. 
)
I was thinking about truck bedliner paint because it sticks to just about anything, and has the same consistancy and hardness when it's dry. Bedliner paint usually has sand in it, but it's in big chunks, and I literally need less than a drop of paint, so I figure I can strain out the grit.
No matter what I use, I'm concerned about what the nasty chemicals in the paint might do to the coating. The solvent could migrate in between the powdercoating and the metal chassis, or soften the coating before it fully evaporates and cause blistering and that sort of crap.
Anyway, I wondered what some of you thought.

. I assume if those are design to use on plastics (as most of scale models are) without erosion, it's probably not harmful to metal surface. The only concern I will have is how well acrylics paint would bond with metal surface. It may not last as long and may need a coat of primer before actual painting in metal chasis.
