If you look at all the reviews of rust preventers on Amazon, the magazine reviews, and recommendations on LJ and other sites, it seems there’s no silver bullet that works equally well for everyone.

I took a look at the Boeshield T-9 you suggested. It looks like it is worth a try. Thanks for the tip.

T-9 is tacky after curing, so someone online (maybe Wood Talk) recommended buffing then putting on a top coat of Renaissance Wax.

I’ve been using the T-9/Renaissance Wax combo this summer and still got some light rust on the right wing of my table saw after about 2 months. I figured the guideline to reapply every 2-3 mos was supposed to almost completely prevent rust, but if that’s the case I think the T-9+wax combination failed. Personally, I’ll start reapplying more frequently on most parts of the saw and will keep using it until it’s gone (because it was expensive), but if I continue to have the same issue I’ll try something else after the T-9 runs out.

In FWW's 2012 rust preventer test, T-9 did okay on tool steel but fared very poorly on cast iron. Camellia oil also didn’t do very well in the test, despite FWW's definitive statement only 10 months earlier, “Nothing works better at preventing rust on woodworking tools than camellia oil.” But a lot of people swear by camellia oil just as they do T-9 and other products.
