I know that these are insanely priced for a real pair, but technically, these are still carbon fiber airfoils. Super lightweight. I have no clue what the street value of these are. I had a couple pairs made. Best reasonable offer I guess?
I left the "meat" on the attachment side so somebody could trim them and drill holes to meet their exact application. In fact, if somebody were to buy them, and intelligently tell me how they wanted them trimmed, I would do so for no extra money, and then reseal the epoxy edge(s) and polish them back up. The current finish is a light polish on UV-rated marine epoxy. If you want them super-glossy, I would suggest a clear coat automotive paint.
