Spraying On Retroreflective Coatings

Thank you for your article about the work Professor Bou-Zeid is doing with retroreflective materials to reduce heat island effect in cities. Bou-Zeid said that retroreflective materials cannot be applied as paint. I have worked with applying retroreflective coatings with paint guns on high-performance buildings I have designed in the past. These have been available for at least 20 years.    

These retroreflective coatings have also been successfully sprayed onto water storage tanks by the U.S. Army in Iraq to keep them from overheating in the summer. Temperature depressions of more than 40° F were observed by the U.S. Army Corps of Engineers compared to uncoated water storage tanks.    

I would be happy to share this information with Professor Bou-Zeid.
