I have a friend that owns a speed tuning shop in Scottsdale. They started printing parts for their customers cars such as air dams and things. I asked if he could make me a couple of radius turnabouts where I could mount a piece of aluminum flat stock. I had the parts in my hands in two days. Basically I told him what I wanted, and they drew up a plan. Today I stopped to pick up the parts and went on to the steel supplier where I bought a section of 5052 1/8" x 79" aluminum plate. Got it home and started cutting it to fit the contour of my roof. Tomorrow hopefully I will install some stainless steel brackets and stainless hardware to secure it all. For now it is mocked up as it will go. I will seal it with Dicor and paint it to match the blue. This will ease any concerns I have about wind sucking under the panels although I already did a 3600 mile trip with no issues. At the very least this may help add some quietness to the drive. It's been so hot here I can only tinker with this when the sun goes down.
