Does one really need to buy the expensive manufacture door gasket, or can you just use the general stove store gasket material? Stove in question is a free standing Quad Castile. Seems like yearly maint to do the door gasket, I was just wondering if the 10 buck gasket and glue would work just as well if not better. Can you glue this cheaper one to the ceramic, or is that the issue? The Quad one hooks into the frame on bars. Thanks all.
