I had great success with a little experiment I tried on cast urethane some years ago. It should work with any kind of plastic:
Get some plain old white latex interior wall paint. The stuff I used was fairly thick, an advantage. I brushed a couple of coats (undiluted) onto some rockwork and let it dry for a couple of days. I had hoped to create a surface similar to that of plaster and that's what I got. I applied dilute color washes and they sort of soaked in and stained the surface. I compared the resulting model rockwork with some actual walls nearby and the overall impression was virtually perfect.
It was really easy and incredibly effective. -- Russ
Thanks Rich and Russ. That's what this all about people helping people to get to where they're going. Thanks for the replies.

Hi, Right on Russ and Rich, may I also suggest that if you can get it, self-etch primer is great. It ignores SUP's propensity to go "like water off a duck's back" and dries almost instantly. I bought a half litre and was still using it 3 years later. It has a greeny yellow colour and takes all paints perfectly from cellulose (of blessed memory) to watercolours.
I reckon Russ's paint on top of self-etch would be bullet proof. Hector
