What if all atomizer coils were "teflon" coated? This material is used on non-stick cooking pans and skillets. Teflon is the Dupont brand name of the original coating, but there are many other coatings now that do the same thing. I was thinking that if coils were coated with this there would much less "build up" of any e-juice gunk over time. Thus the atomizers could be "flushed" with warm water and a final rinse of alcohol and work like new. This would make all different atomizers last until the coil element itself shut down (several months?). Just an idea.
