Undercoating
Milhaud
I agree with you regarding the undercoating process – acrylic doesn't dry hard enough to use as an undercoat IMHO. Currently I'm using a white cellulose primer which dries even harder than enamel to give a good key on the bare metal followed by brush painted Humbrol matt black. (I've tried Nitromors on figures in need of a repaint and the paint stripper gets through enamel no trouble but cellulose is more resiliant).
Thanks for the tip on metallics. As I mentioned in my earlier posts I would have very happily stayed with Humbrol had they not thinned the mix.
