Also, a recent thread mentioned using mylar as a reflective lining but I never saw a suggested place to purchase it. Does anyone have suggestions where to purchase this other than buying a lot of mylar balloons and popping them? :-) What I used for my hood was window tinting film for cars, I got the silver mirror. I think it was about 10 bucks for a roll 10 yards by 1 yard. It's worked real well for me, since at that time I couldn't find a better source. Richard
