Where they are supposed to be selling her here.

Now as a member of glorious /tg i am somewhat experienced painter but havent worked in this scale,the part i didnt understand is do these figures come painted? they say something about colored resin or something but they also say that you need to paint it.
If that is the case do i need to prime it with a spray primer and start working on it or can i start painting on the existing paint?
