It's time to talk dirty, soft ESCI plastic dunked in PVA .. 50/50 PVA to water mix, approx (see below, the Soviets have that suspicious PVA gleam - despite my initial reservations about glooping PVA over nice figures this steps seems to work well):
The Soviets then get the remains of the grey primer .. it almost covers .. but runs out. Time to head off to the shops (see below, about 70% covered but the bases [sand peaking through] tells the true story):
Fully primed (see below, up to full Soviet military standard ):
If it'd good enough for the Soviets the 'big boy' Saxons [28mm of pure Gripping Beast fun and fantasy] want some of the action (see below, note the Humbrol Acrylic spray dries really fast which is impressive):
Well job done. Although I think it is much heavier on the paint than brushing it on - because no matter what I try half of the paint seems just to coat the tile - it certainly saves time!
Note: That this took place outside, based on family complaints of the garage being "stunk out".
