Our front door faces dead west. The front door is large with the wide side panels. The whole thing is made out of wood. The bottom half takes a real beating from the sun I have just finished sanding and staining and now need to select a finish. Does anyone know of a finish with a high UV protection rating. I did all this once before and used an exterior poly. I do not remember the brand. It sure did not hold up like I thought it would. I have a front porch so rain is not a problem.
