I have not heard of the reflective paint but I do know about reflective foil and it works you might want to look into that. I'm about to install it in my detached garage attic. I purchased 4 ' wide rolls it gets stapled to the bottom of the roof trusses that meet the roof deck. So as an example if your rafters are 2 x 4 you have a 3.5 " air gap from the face of the foil to the backside of the roof deck. With good roof and soffit vents it supposedly gets rid of 97 % of heat transfer from the hot roof and no it doesn't cook your shingles. Another way to install it is on top of the insulation. In regards to attic insulation R38 is not too much and is an easy DIY project if you choose to do so. Home Depot , Lowes and others rent the machine and the insulation. I prefer the fiberglass vs. the cellulose but both work fine. Good luck with your project.
