metal

All I know from the marine industy is a bare metal surface can oxidize in about 30 min.
When I protect a metal keel I will sand bare,
wash degreaser/solvent (interlux 202),
Acid wash (ospho)
and epoxy.
all within the 30 min.

A ski with more sidecut should be softer and a stiff ski should have less sidecut.
With less sidecut you pressure the tip and tail to make it work.
with more side cut you stay centerd more and the arc will turn you. Too stiff and it will rebound before the carve is finished.

I'm 270 lbs. Alpine ski coach at GMVS, and I always like my skis soft flexing, but torsionaly stiff. You will find a softer ski wil break down faster.

I have been experimenting with side cuts and trying to get it right. So I came up with a simple formula for direct comparison in how much a ski will pull you into a turn or push you out of a turn no mater how wide the waist is. For instants my latest DD is 140-99-121 (tip-waist-tail) Subtract the ti...
