Snowboard gouge repair

Hi,

I have an older K2 Snowboard with a few gouges on the bottom, nothing
too deep. Would it be possible to wet sand the entire base, fill the
gouges with 2-ton epoxy and resand. I would then respray with some
automotive paints and clear coats then hot wax. The only reason I
would use automotive paints and epoxy is cause thats what I have on
hand. I really don't care about the design on the bottom, so I
thought this would be a good solution and would be free.

Thanks,
Alex
