Suberavid was kind enough to send me a spare radiator scoop he had so I could pull a mold off it. I got a perfect mold, but the release agent didn't release real well when I laid up the first actual part. It stuck in a few places but I was able to coax it out anyway.
Here is the first attempt at the mk IV scoop that collects the air off the back of the radiator for cabin heat.
