Hi, I have a hobby which involves painting miniatures, both platic and metal (pewter). I have a hard time getting the waterbased paint to stick to the pewter models (it goes on the plastics fine), on the pewter ones it tends to slide off the surfaces rather than stick, and when it does go on it chips really easily. The slightest touch makes the paint come right off even when its dry, sometimes small sections just peel off too.
I'm trying to find out if there was something I could mix with the paint before applying it that would make it stick better to the models, and I was wondering if anyone here had any ideas?
Thanks.
