I'm not sure if this is my imagination or what. I decided to try staining a white detail article with acrylic paint (I bought one of those cheap strips of six tiny tubs they sell for kids). I mixed a little bit of the paint with some water and tried dipping the article in it. It didn't seem to work too well; detail material is too watertight I guess (WSF apparently does this a lot better). But one time when I dunked it it looked like some of the detail was sort of *softening* and getting slightly puckered or pocked. Could there be some kind of reaction between the material and even dilute acrylic paint, or am I losing it?
