Our intent was to let them sit and cure until the following weekend when we could meet-up again. But the excessive heat wave continued, and regular 105 -109 degree temps extended that cure time to a couple of weeks.
The micro-balloons have been fully cured; and like us, the planes still await relief in the form of slightly cooler temps and better air quality for us to be able get back out into my shop. (The hundreds of wildfires raging in California have created hazardous air quality for a couple weeks, causing further complications with the progress of our build.)
