I've always wanted a Red Planet Battle Board since I saw a Chaos Blasted wasteland at Golden Demon 1991 24 years later I have one! I can't say it was an easy ride, I made some mistakes in the painting process - mainly thanks to dodgy varnishes.
With Ad-Mech potentially round the corner hopefully there will be a resurgence of Red Planet Battle Boards, they're all the rage.

Hopefully there will be some battle reports featuring 'Ferron Proxima' [my own red planet] coming soon.
In case you're interested the process was a texture spray first [which may have been a mistake as I'm not sure it stuck to the plastic as much as I'd hoped] then Red Oxide primer. Shadow washes with black emulsion, PVA and water mix. Then drybrushed highlights with cheap Vermilion art acrylic, then mixed with a 'Pumpkin' coloured Craft Acrylic for further highlights. Finally a splatter of Bonewhite for added detail and some Gale Force 9 yellow flock PVA'd into the crevices.
