Non-oily rust proofing

rust-proofing

I have a bandsaw that set me back a bit and that I would like to take good care of.

Rust forms quite easily on the cast iron table. In attempting to remove rust from the table, I followed an old husbands' tale about use a potato slice to scrub the surface. I foolishly left the potato to sit and lo, 20 minutes later my table was even more rusted than before! I manage to polish most of that out, with the help of bicarb and a typical scotchbrite-type sponge.

I now have two options:

  • Buff the surface with another power tool, regularly (coastal environment here).
  • Find a way to seal the surface without making it too oily to work wood on.

What's the common/typical way to handle this problem? Is there a treatment that leaves a glassy finish and protects against rust?

For most woodworking tools, there is no particular need or benefit from a "glassy" or totally-rust-free surface. A moderate case of smooth, tight, non-flaky rust is immaterial to the function. I put paste wax on (bowling-alley wax - unlike most floor waxes it does not have abrasives in it - you also want to avoid silicones or you may have finishing problems on your wood products) but until you reach the point of rust-stains on the wood or something like that, a bit of rust is not an issue. If only you'd bought yours used, someone else could have gotten the new off it for you and spared you the agony of seeing it become a tool in use, rather than a shiny thing that hasn't been used.

Most of the tools that get moderate use have a tight blackish layer - not shiny silver, not rusty orange.
