I've been doing some very nice curves on a very old fiberglass monocoque Lotus Elite Type 14 with custom streamlining aerodynamics. The 32" Ultra Flex Block is absolutely phenomenal in perfecting all those curved and reversed curved panels! In the lesser curved areas like panel to panel with the door and boot lid I start with several sized Flex Blocks and 1" rounds and true the form very quickly around about 80% of the car. Then I go for the 32" Ultra Flex Block to easily dial the whole car into perfection! This after doing years of repairs on stress cracks, normal bodywork and creating NACA Ducts, flush fit front and rear windscreens, recessed headlamps with headlight cover fitments and directional signal lamps as well as a whole "Costin Nose" refinements as well as a double reverse angle Kamm tail construction and body seams, makes all my hand sanding to bring it all together so much easier with unbeatable laser straight curves you just can't achieve with anything else! ***Please pay attention to promotions, as I also received a FREE Fisheye Filter with my purchase!
