While the stainless look is nice, I've been toying with the idea and visual of a "Copper Kettle". No pracitical reason other than looks and the ability to then use that name in reference to the "brewery". (navy diver thing). That being said, has anyone else come up with an inexpensive way to put on a copper covering on a keggle? I am in the process of building a 3 keggle HERMS and was thinking that I'd just copperize the MLT (to avoid the flames of a burner doing bad things to whatever copper trick I come up with). I've thought foil, tape, paint... Was interested in knowing if anyone else has done something that they'd like to share.
