undercoat them so that paint will permanently stick to them? I've lots that I wish to add to 1/72-scale dios.
TIA. George, out...........
Buy the newer ones that come in harder, gluable plastic.
Italeri for example is going with a much better plastic than the old rubbery Airfix stuff.
Otherwise, a good washing, priming, and good, solid base coat are your best bets for a good finish.
You can't handle the figures heavily, especially things like guns, as the paint will flake off.
