Well I did.
For 15 quid, it's worth a go. I can only tell you OT that I was a massive plastic-sceptic - and truthfully, I've bought one or two other boxes of plastics and I'm not impressed.
But these particular figures are simply amongst the best I've ever worked with - material immaterial!
Mmm. Might take a look then. Then again, so much to paint; so little time available for painting...

W&N Galeria matt varnish.
Thought that's what you use.

Mine always dries with a slight sheen.

(Still happy with DR, but like to know of alternatives.)
