Re: Wax Coating Plastic Frames...
I went through wax a lot faster when using the foam roller. And the bottom of the cells did get full, some of them, the bees still drew it out.
The chip brush the wax coats nicely and it takes less.
I use the crock pot with water, I dip the brush deeper to warm it, then up through the wax. We keep our house cool in the winter, the wax hardens fast on the brush.
