[Michael O'Brien]

Hi, Ben--

Paint may improve reflectivity but not emissivity of asphalt, so it will still get hot.

It gets really hot in the summer, but I need to work in there, I know I can buy a silver coating and there is a white coating (but it says it won't work where the water puddles),  What about painting it? Would regular oil based or water based paint work? I believe I can get free paint at the recycling center.
