Thanks everyone. But the problem continues
I washed the figures with LDS (the soap kind:) a couple of times actually. But still the primer peels off. There is a shop that sells GW stuff. I asked the guys there about it and they said they also used Valeejo primer (brush on). They showed me their miniatures (they are not miniatures I think, they are giants, didn't like them:) and I saw that you have to "try to peel the paint" off, it doesn't peel of on itself like my vikings. I washed the Viking king figure with a special anti-grease-oven-cleaner thingy stuff but still... Despite the washing, the primer, satin varnish (two coats!) and matte varnish, last night I accidentally peeled off the paint on his chest.
Excuse the rattle, here are my questions:
1: How about using extra high gloss varnish as primer and then just simply undercoating with regular black/white/grey paint? Here is a link to the first painting tutorial I read
http://beepdf.com/doc/120378/painting_1_72_scale_plastic_soldiers.html. In this tutorial the painter primes the figures with varnish and then paints on white undercoat. Would that work?
2: Am I simply expecting too much from soft plastics and primers? Do I have to simply be more careful and not let anyone play with my figures? (I don't want to be that guy:)) I mean, is this the natural order of things?
