The surface of wax is draggy. How about lightweight spackle as filler, shape and sand. Then a thin coat of epoxy or something else hard and shiny over it? It can be dug out with a pick after you are done. Clean it up with a dremel once apart.

That's totally stupid and crazy. I can't believe I haven't done that. I'm headed to my shop.

Greatest response ever.

Id also think that a little epoxy and a lot of aerosil might be good and easier to flake/sand off? Though poly over epoxy is probably good (Bondo is poly, yes?)

For only about 2 hours of work (I only wet-sanded to 600grit) I think it is totally worth it.
This morning I surfed a wave I haven't in a while, so the jury is still out about whether drag is noticeably less (it didn't transform me into "The Hamma" or anything like that).  I did have a really great session though!

It should be noted - the foil was WHISPER QUIET, I mean zero sound.  it was uncanny actually, I hadn't realized how much I've gotten used to the very slight whistle and slurping sounds of the foil.  All 100% gone.  I used to think the GL was silent in comparison to the IWA/M200.

Considering that it takes energy to make the wing whistle this is encouraging.  I took off next to you last week and my rig was SINGING.  I am now wondering if the sound is coming from the tail feathers or the front wing.  I suspect the tail.  Your solution could be a great one.

For those of you waiting on baited breath for a ride report - I am sad (but not surprised) to report that the difference in drag is not noticeable for me.  The change in sound contributes to a psychological sense that the foil is riding smoothly and effortlessly. But I don't believe it is noticeably faster nor is pumping noticeably easier.  If I ever get a new foil setup, I'll still probably take the time to fair it with bondo because 1) it was easy to do 2) I like the change in sound 3) I rarely take apart my foil 4) every little bit helps

As I said earlier, you're not likely to feel a difference, but that doesn't mean it doesn't help.
