So I mistakenly bought a tub of rutland "regular body" furnace cement that was not black. It's like a tan color and is not wet, more like a puddy and very stiff. It smears well and you can roll it into a long sausage to push into a crack. Is this stuff proper for the inside of a woodstove? Has anybody used it? The color is very close to the OEM hearthstone stonedust cement. I actually liked using it much more than rutland black.
