well I just pulled the side windows out and it turns out this thing is made of fiberglass. It is about 1/8" thick. I guess it just sounded like thin aluminum. I am going to start putting some lines on it and cutting in a little bit then I guess it is time to learn how to fiberglass. I will post up pics when I make some more progress.
you can get some good how to videos off the internet... e-bay... most of the ones I have are for car stereo installs... but it at least teaches you the basics... I think I payed $20 for 3...
