So I had my Hudson painted with Valspar polyurethane topcoat 840, and the painter gave me a small amount of paint leftover in a can together with a can of leftover activator. Now, a couple years later, I'd like to use it to paint a couple of extra parts rather than buy rattle cans in the same color from Paintscratch. So my question is, can I mix the color and the activator and brush paint some small parts rather than spray it, since I don't have any spray equipment (Do I hear laughter?)? If so, is this stuff so toxic that I should not use it without a mask, filter, body suit, etc? If so, I'll just throw it out.
Thanks for answering.
