Drag reducing paint / coatings on lower unit
Has anyone ever experimented with friction reducing coatings and / or paints on lower units to reduce drag? I've read about sanding techniques to create a surface layer of water molecules, thus reducing drag, but for those wanting to keep it painted are there options that do anything to reduce drag? I know about everything has been tried on hull bottoms and there are mixed reviews if it really helps performance, but wouldn't these coatings also improve performance when applied to the lower unit also?

Turbo, here is a link to one of the discussions:
Sanding a lower unit for speed
There are many other discussions of this on OSO and other forums as well. This is the last step after thinning and blueprinting a lower unit. Goes hand in hand with blueprinting a hull and sanded finish on hull bottom being faster than waxed / polished.
With all the nano-coatings and finishes now available I would think there is some type of a hydrophobic type coating that has been tested for this. It probably has in the racing world.
