Rutland high temp silicone for a temporarily fix?

[Stoney Meadow Maple]

The front panels of my Vigilant is leaking air, so it is time for a rebuild, no biggie there, but in the meantime it is hard to control it, it is sucking enough that unless the damper is flipped to horizontal burn it will run away, i used furnace cement to seal around the top edge and it worked great until it fell off.. no surprise.
Will the Rutland 2,000 degree silicone really hold up? Is there a better product?
I seem to remember having alignment issues when I reassembled it last time, I got it on right, but I think I squished the cement out of it out when I put the top on.

I don't think there is such a thing as a 2000 degree silicone. If there is, I would like to know about it so please provide a link.

Are you talking about stove and gasket cement or furnace cement?

I once use some furnace cement for metal to metal, and it was surprisingly difficult to break apart. I thought I would be able to tap the pieces apart with a hammer but, no way. If you clean off any ash or creosote and rough up the area with coarse sandpaper, it should stick and would last for a while.

The stuff I used was Meeco's Red Devil furnace cement from Menard's. Menard's gets most of my money.

You are right, when i went and looked st what i had, it is 500 degree silicone and 2,000 degree gasket cement. It seemed pretty hot for silicone, which is why i was nervous. I used stove and gasket cement seal the gap, and it worked, but after a few heat cycles fell out. What’s the difference between furnace cement and stove and gasket adhesive?

I don't really know. I have only used furnace cement and refractory cement. Both seemed about the same to me but one is for masonry and the other can be used on masonry and metal.
