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.
