Nope.....HDPE high-densitly polyethylene...3/16". Pretty slippery
stuff, but I know there is a lower-friction product out there, just
haven't looked beyond what I could get locally. I used this stuff on
my first set of skis, went thinner to save some weight on the next
pair...this pair...and now I'm just modifying them to shed some snow.
The HDPE works real good under all the conditions that I've put them
through over the past three years. There was a product that was
touted as super slippery...some kind of orange "safety-something" but
getting it cut and shipped here (Michigan) from Washington state, was
a bit pricey, so I passed. I rather liked the orange color as it
would match my plane.
I just pulled a trial run of two plies (of some old Kevlar) for the
covers, and the result is good enough for me to want to try a trial
run in carbon fiber or S-glass.
I'll keep you in mind for a source of info on skis, Barry. : )

aluminum?
If so Get them Hard Coat Anodized with a Teflon coating. It makes
it VERY difficult for the snow to stick.
The thickness will depend on the type of aluminum you are going to
use.
2024 you can only hope for .001 to .0015"
6060 & 7075 you can easily get .002 to .003"
DO THE HARD COAT AFTER ALL HOLES ARE DRILLED
If you are interested in this let me know and I can fill you in on
the operation and tricks.
I did this for a Piper Cub on Skis.

HDPE is no where as slippery as hard coat w/Teflon BUT... it is a very good material for ware and I'm sure you made it a replaceable covering. Goo Job

Yes it is replaceable....flathead screws through the material and
through rosette-welded small tubes through the chrome-moly frame.
I always find something to modify on these skis. The first year I
built them I made them "wheel penetration" skis where the wheel
protruded through a hole in the ski, but last year I made up a new
set that is similar to the Federal Skis, where the wheel sits in a
notch in the ski. In this manner there is no ski material...frame,
bottom or otherwise..to cause drag behind the wheel. Anything behind
the wheel acts like a cheese slicer and just scoops up snow, etc.,
and deposits it on the rear of the ski, I have found.
