Been making a CIA SAD Team with 21st century figs and when i was done with the paint job and the figures were dry; I sprayed the dullcoat to get rid of the shine. Next thing the figures are white like they have been through a blizzard. It's cold where I live could that be the reason? I don't spray alot. Was using Tamiya Dark Yellow, Testor's Desert brown and a mixed combo of Olive Drab and Black. It also turned the figures head's white which was not painted. What would be the cause of this?
