New to gunpla. And i put most of it together and was hand painting. Thinned out acrylic paint with acrylic thinner. And paint a few layers giving 10 to 15 minutes between coats. Is there a easy chemical to soak it in to remove the paint and try again? Tried some simple green hasnt even made it budge. Its like the first few layers went great then it starter pooling in places while drying to make the paint uneven. Im hand painting btw.
