I checked the hardware store again, starting with the wipers/seals for the bottom of doors. The wipers had a T or Y shape for sliding into a channel; could work. I continued to work my way down the isle, looking at every single item again. I found some garage-door seal, which I could cut in half to get the wedge shape I wanted. Then I found a P shaped seal. Imagine a P laying on its side, with the round bump 1/4" tall. If testing works out, I'll probably go with the garage seal. It's the desired shape, and it's black, to match my trim.
Extruded seal posted above: $2/ft, wedge shape, black EPDM
Garage-door seal: $0.70/ft, wedge shape, black EPDM
Door wiper: $0.28/ft, Y shape, gray unknown
P seal: $0.20/ft, P shape, self adhesive, brown EPDM
I bought the P seal for three reasons: 1) price. 2) self-adhesive for fast A-B-A testing. 3) while not the perfect wedge shape I wanted, I figure the 1/4" radius is much better than the 6-10" radii currently on the back of my car. And it's about the same radius as the trunk lip on more aerodynamic cars.
Yes, Darin, I'll do A-B-A. I keep thinking the same question you ask in the VG discussions. "Why not a lip instead of VG's?". Here's the plan: make an 11* jig and mark all around the backend of the roof, sides, trunk, bumper, etc where the body is 11* from centerline. Attach lip where marked.
I'm oncall this weekend, and it's raining/snowing here anyway. I've got a river-trail cleanup next Saturday (1st & main, RH77), but hopefully I can get some testing done next Sunday. I really doubt the air is reattaching on the trunk lid, so I think a lip there will be wasted. Perhaps some tuft testing is in order before lip testing. Any other thoughts?
