Re: what is a good paint for exterior wood?
Did you use FLAT paint? What version of SW paint? They have some low, middle, and high grade paint. Most of today's paints take up to 30 days to cure so they are very vulnerable to getting marked up if bumped or touched during that time. What kind of prep did you do on the walls? Did you sand? Did you remove the dust? Did you use any kind of cleaner that left a residue? All of these can affect the paint film in one way or another.
