I took a gamble and added a layer of solarflex 287 to the roof in early October.
The directions say not to apply if there is a chance of dew within 48 hours, so I have no idea why they would bother selling it in Washington state.
Anyway, it is 82 out today and while the days are shorter we are supposed to have dry weather until Friday.
Hopefully tomorrow it hasn’t turned into a big runny mess. I’ve read some stories about it doing that.
Its currently 3:30 pm so a few more hours of direct sunlight.
