I've already searched this and have seen a gazillion threads on it. I've tried everything and nothing really works unless I go around my shop every single day and wax or oil anything that's cast iron. I live in Florida on the coast and on a good day it's unbearably humid (I'm originally a Hoosier and even after being here for decades I've never acclimatized).
So frankly, I'm kind of sick of cast iron and would take almost anything else as an alternative for power tool tables. I don't care how "stable" it is.
I'm wondering if anyone has ever just painted the tables with Rustoleum or something and been done with it.
So far I've used T-Shield, 3M boat wax (intended for boats in salt water), beeswax, furniture wax (about a half-dozen different types), WD40, that rattle can sealer stuff (top kote and dry kote). At best some of them last a couple weeks IF the tool sees no use during that time. T-Shield did the best but I have to clean off the table with solvents before I put wood on it which makes it even more expensive (solvent plus having to reapply it all the time).
So yes, I'm very seriously considering painting all my cast iron tables. Has anyone done it and if so how did it work out?
