I suspect that if I had allowed the wood to "cure" for a year or two it would have done better. I am gonna make some real boards this winter. The 3 piece with the router joints. Will let all know how I do. One thing, paint the back side flat black after you drill the hole. Tape the front totally before spray painting. Let it sit over nite and then stain and clearcoat the front. They will look great if you do that.
