I kind of worked it the other way. I glued a strip of trunk sealing
rubber, left over from an auto restoration, to the bottom of the water
radiator and lowered it enough to mash the rubber tight against the
cowl, then filled the sides of the cooler with foam and siliconed them
in. Nothing gets past without first going through the cooler. Temps
will go up on hot days, but nothing above the limits...
Jeff - Baby Blue... Back together and flight testing this weekend.
PS Fred: Fairing tests will be complete, though not permanently
installed, for Rough River, barring any problems with the bird...
