@sane max agreed. The plastic which some HaT sets are made out of ( softer, more Matt surface which feel slightly ‘sponges’) Seems to really take paint well and I’d be surprised if acrylic chipped off, is really good. Some manufacturers are still using very shiny PVC and those are the ones I think might shed paint.

your wargame journey is eerily similar to my own!
