I need to ship some kind of insulation overseas to use in a hot, sunny climate. The buildings are existing structures with corrugated steel roofing. Ceramic insulating paint caught my attention. Is it really all it claims to be? Where can I get it in small quantities (enough to cover 4,000 sq. ft)? What is the cost? What do I need for the application? Materials and tools will be hard to come by, so I am looking for a cost effective solution. I've checked out Supertherm and Sunland Coatings, but I have not found a soluton for private home owners.
