Painting shiny plastics?

[Thuseld]

My terrain is a De from yoghurt pots and other shiny plastic. They don’t tale paint well. I find it scratching off. Is there some thing I could do to it beforehand to stop this happening?

I also find I have to layer paint a few times or it really streaks.

What are you using as a primer?

A hard primer will help – Krylon or Rustoleum is my preferred one. If even the primer is not taking on a surface because it’s too smooth, try giving it a light going over with fine-grit sandpaper first – it’ll take it from a smooth down to a kind of “frosted” consistency but will make the paint grip much better.

I am a Humbrol kind of guy myself.
Mostly as the local Hobbycraft stocks it.

White for infantry.
Brown for everything else.

The above works well, also matt varnish pre coat or watered down wood glue pre coat.

Absolutely.  And for finer detailed pieces, a toothbrush or nail brush with baking soda and water will put a bit of abrasion on pieces.
