Hey digibeam, my process was to autocad a 2/3rds scale of the Dark Knight Tumbler through photos then generated paper patterns. I take the paper patterns and create a cardboard model. Then I cut the fiberglass panel and use pics to duplicate the angles and position of the panels. I use a technique called tabbing with bondo to temporarily hold the panels in position. Then I flip the individual panels over a fiberglass using a 3/4 ounce mat in case I need to adjust them. I then create a frame holding the panels in position. I try to triangulate the square tubing as best I can for strength. Once this lightweight frame is done its so much easier to see where I can improve the heavier gauge chassis. The panels will be sanded, primered then sharpen up the edges then painted a semigloss black. I will then wax and create molds out of the finished painted panels. The frame and mock up panels will go to a friend. The chassis and pulled fiberglass pieces will help me build my 2/3rds finish vehicle. That's how I built the Tribute Rumbler. I'm trying to build a smaller but more accurate replica at about the go cart size. Haha bet your happy you asked. Thanks for the questions I appreciate the interest.dave
