Cast iron routing table....

[Richard]

Has a couple rust spots starting...

What can/should I use to coat it with to protect it?

I'm guessing something like mineral oil? (light coat of course)

How about something that I already have on hand, peanut oil?

I like paste furniture wax. Clean up the rust spots with steel wool then apply the wax, it protects and the work piece glides across the surface really nice and smooth.

Yep, don't put any kind of oil on it as it will come off on the wood. Use a wax.

Yep x 2 ... I use paste wax on all my cast iron wood working tool tops.

BOESHIELD T9
T-9 Rust Protectant, 12 Ounce Spray, was developed by Boeing Aviation for long term metal protection on aircrafts. A solvent and paraffin wax formula, it penetrates into metal pores, displaces moisture and dries to a thin film that will protect your woodworking equipment for months. Since it contains no silicones or Teflon and dries completely within a few minutes, it will not transfer to wood surfaces or interfere with subsequent finishing. The 12 oz. non-fluorocarbon spray is ozone safe.

Get it smooth and shinny by whatever means you wish. (Belt sander works for me) Then apply naval jelly or phosphoric acid and wait several days before you make it shiny again. Then a wax. I use floor wax but there are many others that would work. Real serious and a coat of clear expoxy might be considered.

I'm guessing with the T-9, I should first put some elbow grease into the growing spots prior to applying it?

MinWax paste wax is what I use. Cut off a chunk of it and put it in 2 layers of cheesecloth. Rub it on the table top, take a break, and buff it out. It lasts quite a while.

With the T-9, I sand all my metal table tops and clean with paint thinner or brake cleaner. Spray on T-9 and let dry for a few minutes and wipe off. Clean top and recoat every few months. Helps the wood slide on the top. If I am doing a lot of wood working I will spray some on and wipe off to help the wood slide easier.
