Hello, I'm curious as to whether it is possible to enamel a plain iron stove after it has been already assembled, in the case of buying one from the second-hand market? I guess it would need to be disassembled and shipped to wherever you have your enameling done. My second question is whether any of the stoves have a secondary air combustion system, as I haven't been able to find anything about it online. Also a point of concern is the lack of a seal around the door to the firebox, how do you effectively control the fire if you cannot completely shut off oxygen? I would love to purchase a new little cod in the exact color I want, but it would seem that other small wood stoves of a similar price come with more features, albeit less pretty colors.
