Hello, Terry. Effectively every time I apply a coat of paint I let it dry completely, if we do not let it dry every time we pass the brush, we would change the paint so it would stick and possibly be satin. It is best to let the paint dry and reapply, dry and reapply until the color of the palette is put on the figure only so we will know that the paint layer is well applied and belongs to that rise in light, a Once the figure has the same applied color that is in the palette we can move to another rise.
I always use small wells for painting I think it is better controlled and for me it is more comfortable, I have used the wet palette several times and I do not get used to it, I do not know, I guess it will be a matter of taste.
A greeting.
Alfonso.
