why not change your coat of teflon for a ribbed one. We did some experiments with ribbed coatings to reduce drag on our mid-range fleet, just like the transatlantic/circumnavigating yachts have on their hulls. Though I'm not sure what the results were, this was about 4 years ago.
Only thing is the ribs are very good at trapping dirt, so there's the problem with this solution. So I've got me coat and I'm out the door!
