Subject: refinishing the front door
Being in Phoenix, it gets really hot. Our front door is in an enclosed porch. So it never gets direct sun, nor does it get rained on. But the exterior finish is getting dull and rough. Interior is still smooth and relatively shiny.

The door has multiple recessed panels. My concern is that when sanding off the old finish, I will round the edges of those recessed panels. The flat bits are easy with an orbital sander. I'm going to have to do the recesses by hand. Which heightens my concerns about rounding the edges of the panels. Any advice on how not to round those edges?
