I've been lucky enough to be sent some of Duncan Rhodes' Two Thin Coats' Paint Range to test out, and thought I'd do a series of postings about my thoughts.
First up is his White Star and Doom Death Black - which I've used as primer for some 40mm 3D resin prints I made. With just a single application I'm very happy with them, tbh.
I also used Emerald Green as another prime which seemed to work very well too, and Sir Coates Silver (over a Citadel Abaddon Black prime - didn't want to waste my sole pot of Doom Death Black).
If interested, then you can find out more in this series of postings here:
