yes, I would even say that a good ceramic setup can be permanent (maybe a bit adventurous). I have 2 DIDs that I don't look at as rebuildables anymore. When I feel performance is slowing down, i fill the tank with water, do a wet 'boil', slowly emptying the tank to clean the wick pores then finish with a dry burn to clean the coils. good as new. I think the "rebuildable" concept has been redefined with these wicks.
