It's probably not great to admit but my recent rework of my 18 year old screen porch had me replacing the painted (white) cedar boards with a PVC board. Getting too old to climb ladders and scrape paint and too cheap to pay someone else. But with these cedar boards that are still in good shape I was thinking of building some Blue Bird houses and the 5-1/2" width works great. Question is should I or is there reason to remove the paint on the one side and edges? Seems I read somewhere that these BB houses sholdn't have finish on them. I can run them through the planner and trim the edges on the jointer if needed but just thought I'd check 1st.
