...I used Dupli-Color black, I remembered Henry's famous quote " Any color you want as long as it's black", and because black dries faster. It gased out over night and then I kept a tight lid on it. I started with a small drop of glue and no reaction from the girls, which is unusual then a little more and a little more. I started thinking how they use nail polish sometimes in the car so, I got my brushes and paints out and went to town, no problem. Thanks for the comment.
