Hi Chris,
     I paint My Pierco frames with melted beeswax using a foam paintbrush.
You do not need a thick coating of wax just brush across the cell area
quickly. I usually apply more to the top area than the bottom. I have good
luck with Pierco but last summers nectar flows were terrible and the bees
drew them out poorly. In September though, I had better luck with them
finishing them.
Hope this helps,
