Northeast USA (New England) is Vermont, New Hampshire, Maine, Massachusetts, Connecticut, and Rhode Island. I was just making a point that spraying paint cools it down. If this is done in a hot and humid environment, that cooling spray effect will condense water from the air onto the object being painted, ruining the paint job. If the ambient air is cool and much drier, there is not enough moisture in the air to condense, so no damage is done. I have experienced this enough so I know not to spray paint during hot and humid days. Reviewing this discussion now, this specific problem could be humidity related after all. 85% RH seems quite high, but we also don't know the air temperature of when the painting took place. Expand temp was 60 to 65 degrees
