These figures, represent the percentange of light reflected.
Mylar 90-95
Flat white paint 85-93
Semi-gloss white 75-80
Flat yellow 70-80
Aluminum foil 70-75
You'll see that Mylar and flat white paint overlap each other. If you use the Titanium flat pure white, it is identical to the reflectivity of Mylar. The paint has several advantages. It is harder to hurt, easier to handle, less expensive, can be redone easily, can be touched up in the case of damage.
Any good paint store has the titatium flat pure white. If you look at the stats for the paint on the manufaturers web site, you can get the reflectivity stats as well.
