AMIG 2253 U-Rust Black Oxide Transparent 40ml.

MIG2253 AMMO BLACK OXIDE TRANSPARENT

AMMO's new U-RUST range is a new formula designed to create rust effects
on your models. It is not regular paint that simulates a rust finish,
but an actual oxidation process, and it would be very difficult to get a
better result than easily achieved with U-RUST. AMMO has managed to
adapt an ordinary chemical reaction to our scale models.

Product formulated to create real black transparent oxide. Ideal for
simulating dark and see-trough zones of oxidation. Provided in a
convenient 40 ml (1.35 fl oz) container. Compatible with the entire
U-Rust range.
