What is the best reflective surface!!!

I can't remember the source, but somewhere i remember reading that mylar reflects like 90-95% of light. flat white paint reflects like 80-85%. Don't quote me. I do remember that the difference was negligible. Save $$$ and use flat white paint. GL

Thanks mountain

that diamond mylar looks nice...

a gallon of cheap flat white paint costs around $15 and covers 1000-1500 sq. ft., depending on surface. Also, diffuses light, no hot spots.

The thing to remember about flat white paint. Best to SPRAY it on smooth surfaces. The smoother the surface the better the reflection. Also make sure to give it a couple coats to make sure the paint is nice and solid. Mylar is for NASA, flat white is for farmers.
