Could someone suggest or explain to me why the paint on the inside of my Quad cb1200i peels on the first light of the stove. The burn pot and baffle plates peel every time. I use high temp stove paint and it does not seem to matter. It is almost like the paint is not adhering to the metal. Also, suggestions on when to replace the thermocoupler cover. Mine is in it's third year and it has some surface wear on it. I painted it, but that did not last in the first 5 mins of the start up burn. Any help would be much appreciated.
