I'm looking for a source of "riblet film". The research I have done always leads me to studies done by NASA, aircraft applications by Boeing and its use by the racing yacht Stars and Stripes. The source reference mentioned is "many companies including 3 M." I have not yet contacted 3 M, but going through their product list, I have not found this product (although going through their extensive product list has awakened many new ideas. It's worth a look). I almost think it is proprietary because of its connection to an America's Cup competitor.
Has anyone used this stuff and who would be a supplier? All it is is an embossed, self adhesive, some sort of plastic, sheet. But the size of the riblets, I'm sure, is critical.
