This is my second summer in my shop.
Last summer I could not keep surface rust off the cast iron.
What do you guys use to prevent rust on your cast iron surfaces? I will lightly wet sand with mineral oil and 500 grit sand paper then put Johnson past wax on.
However, I was having to do this about once a month, sometimes more frequently.
My shop is a detached building from my house.
Looking for a better option.
Thanks,
Nick
