Tamiya Panel Line Gray 40ml

The bottle top doubles as a brush, so I just dabbed it along the panel lines and let the capillary action do the work. Gray is subtle enough to read as shadow on white plastic without looking dirty.

The pre-diluted viscosity is perfect straight out of the bottle—no thinning guesswork, just dip the brush and let capillary action pull it into the recesses. A single pass gives that subtle gray shadow that makes panel lines pop without looking cartoonish.

The capillary action on this stuff is unreal—it just flows right into the recesses on my gunpla and dries without smudging. One pass and the panel lines look like they were actually engraved, not painted. Definitely grabbing the black and brown bottles next.
