Thanks for info . I raced NASCAR mini stock and dwarf car for 6 yrs. I have a vacuum forming machine to make lexan bodies for rc cars. I bought these sheets from a local glass company, these were higher quality than i normally use.we had a110 temp day when I made mine, got lucky. I had a pattern, that is the secret ! I used racket straps to help form it. I then used my heat gun for monocote covering for rc planes. I used my temp gun to make sure I did not exceed 300 degree. If you heat it to much without baking the complete sheet at 200 degrees, you can get gas bubbles. It took me about 4 hrs to work the sheet to form/ installed. The guys on this form is great!
