Can I use stove cement instead of a gasket? I keep tearing up the gasket, cleaning the glass when I'm burning wood before it gets cold enough outside to burn coal. I'm thinking a bead of high temp rtv around the glass to door surfaces.

Personally, I'd stick with the gasket & just be more careful cleaning the glass.

I would tend to agree with FF, but I did seal a crack in my ceramic with RTV & it worked. Not knowing what your stove looks like it seems that maybe a thinner (with wise)gasket would do the trick. Wouldn't you mess up the RTV the same as the gasket?

I agree with Fred too, just be more careful ;) but if you want to seal it with sealer I would use this instead of rtv (Seal It Right Direct Vent Appliance Sealant ) it has a 800 temp rating and it easy to work with. I seal my flue pipe joints with it.

I'm as careful as I can be, I'm anal about clean glass I love watching wood burn. I run the paper towel to the edge when it's cool and run into the gasket no matter what I do, I used to detail cars so I have to go to the edge, it's a habit at this point. When it's burning I use 000 steel wool, same result but slightly more harsh on the gasket.
Do I have a higher risk of cracking the glass trying to use sealant or rtv? That stuff dries flexible?

Exposed gasket isn't doing anything, so why not just cut it off flush with a razor blade?

Permatex Ultra Copper is the stuff to use on stoves, for many purposes. Rope gasket, however, will outlast any RTV - it's just a stronger material. Can't cheat physics. ;)

They've changed the packaging recently, as noted in the pic below:

so here's what I did:
I tried cutting the gasket, but it frayed worse, so I used the copper RTV, let it cure ~24 hours. seems to be holding up well, It may be a seasonal fix and a huge mess to re-do it, but it does work and is holding up well to the 000 steel wool glass cleaning. I decided to skip the furnace cement because I thought it's lack of flexibility would crack the glass.
