Citadel Spray – Mechanicus Standard Grey (10 oz) is a premium spray primer from Games Workshop that works as both a primer and basecoat in one. Specially formulated for use on plastic, resin, and metal miniatures, it provides a smooth, even matte finish in the signature Mechanicus Standard Grey shade, perfectly matching the Citadel Base paint of the same name. This makes it easy to cover large surfaces quickly while maintaining color consistency across your models, with any missed spots easily touched up using the matching base paint.
