Howard Feed-N-Wax wood polish and conditioner - my new solution for treating the sides of cradled panels.
Recently I decided to stop painting the sides of my encaustic paintings. The process proved too time consuming, for one thing. A bit of research led to this product by Howard. It's much easier, faster to apply, and more economical than primer and black paint. Best of all, I like the results. You can see what it looks like applied: middle image shows before (painting on left) and after (painting on right).
Howard Feed-N-Wax is available on Amazon's website, where I purchased mine.
