Army Painter: Aegis Suit, Satin Varnish

The Aegis Suit satin varnish will protect any tabletop or roleplaying miniature and model from the wear and tear of the battlefield.
Unlike the anti-shine matte varnish developed for Quickshade, the Aegis Suit will leave a slight satin finish on your models and is ultra protective on any acrylic surface.

The 400ml (14.1 Oz) army-sized aerosol can gives you plenty of spray paint to prime even a large army.
