@i:
is there away to make them not chip??
Even perfectly painted miniatures can chip or flake from very minimal use (finger sweat can be enough to make the paint itself start to “sweat off”).
Sealing them with a spray varnish is the best approach. They come in the several finishes similar to paint - matte, satin, and gloss. I recommend using a matte or satin as gloss is a bit much. Also remember that most varnishes make the color of your paint a bit darker, so it’s best to paint them a shade or two lighter.
I’ll post a comparison between varnished and unsealed paint jobs after I finish the full ANZAC series.
