Customs paint help (blindbags)

[AubadePrism]

This used to not be an issue, I use acrylic paint and when I attempt to paint a blind bag pony the paint gathers as if it's oil on water. Oddly enough the blind bags I purchased a year ago do not do this. Is there any way to stop the paint from doing this without taking off the eyes?

Primer maybe? Wash the blind bag because may be there is oil on it. I'm not an expert though....

some acertone might help. I suspect there's probably oils or other residue on the plastix that's making it repeal the paint.
