So I recently decided to give my WIP custom a new coat of paint because the last one was lacking... the thing is, I no longer have the old acrylic I used for it and I cannot find it in stores anymore, so I just mixed some paint to get almost the same shade. Thing is, despite technically being dry (i let it dry for days...) it still has this sort of stickiness that attracts dust particles like honey attracts flies. I suppose this will not bare well for the following years. What can I do?
