Hi Pete

The gondola paint should work well on the cast iron rollers. The varnish
on the hopper that might flake off into the must is in all probability
inert and will make it's way to the bottom and not into the wine.
Stripping the varnish from the hopper is a good idea from an aesthetic
view point. If it is oak you may want to think about coating it with
the gondola paint or an FDA approved epoxy paint. If it is red oak
rather than white oak it could impart some nasty (think cat urine)
overtones to your wine. It probably won't but it is better to err on
the side of caution.

Definitely rewire the motor for grounding and then make sure the circuit
you plug it into is also grounded. It is easy to get shocked during the
crush.
