funnyhow he forgot the best product available.. ?Here's the chart of percentages of light reflected from Jorge's latest:
Foylon 94-95
Reflective Mylar 90-95
Flat white paint 85-93
Semi-gloss white 75-80
Flat yellow 70-80
Aluminum Foil 70-75
Black < 10
There ya go, and when you buy the flat white paint, tell the paint guy to mix in a packet of fungicide.
