As some of you know, I'm in the process of rehabilitating a older Keystoker 90 direct vent stove. Most of the work so far has revolved around wire brushing and scraping lots of crusty junk and rust off the interior of the stove.

Most of the real wire brushing has been done outside with the angle grinder and wire cup wheel, but quite a bit of hand scrubbing was done in the garage.

Well, today I walked by the table saw and noticed the top of the table completely covered in rust. It was NASTY. This saw has been in the garage for almost 2 years and hasn't suffered as much rusting of the top in that entire time as it has since the stove arrived.

Fortunately, I had purchased a tool table restoration kit, so I busily got to work removing the rust, and there is a coat of Johnsons Paste Wax drying on it right now to avoid futher rusting.

I can only surmise that the residual ash and rust I kicked up in the air, settled on the table top, and proceeded to start rusting the top ASAP. Amazing. No wonder the inside of the Keystoker looked the way it did. I cleaned and brushed it all out and painted the entire inside with high temp paint and hit a few other areas with LPS-3. Even still, I see rust forming through the paint in a few spots. I sealed up the openings and put my trouble light inside the stove to hopefully keep it from rusting further, especially through the cold/warm spells of spring and the rainy humidity.
