After that most solvent based paints will work fine especially Acrylics or epoxies. Beware of thinning too much with Acetone of MEK which can affect the surface of the model.
Should I sand everything, or just the nubs? Also, is it unusual to see white hashmarks after you have sanded? If so, I assume that acrylics will cover it. Lastly, should I add a base coating before applying paint?
