Hi all, Just my 2 cents on this subject. There's a lot of info on the net on this so I'll not even try to elaborate.
Air over air causes a lot less friction than air over metal, fiber glass or whatever. Therefore a very slight rough surface on i.e. a wing (pinholes) will produce less friction than a very smooth wing surface and therefore also higher top speed. You actually want dull surfaces for more speed as bright smooth surfaces are purely for appeal and not for speed. The air clings to the surface and this is the exact opposite of what you want. I'm convinced that if you take sandpaper and apply to your KR giving it a dull, non shiny surface (not nice to look at), you'll get the speed increase you're after.

I do know that fiberglass gliders fly considerably better when they are clean and waxed, but they have a whole lot more wetted area than a KR and competition gliders likely have much more critical airfoils than the KR does.
