Ummm Rick, i dont wish to go into any theological discussions, but water cannot be distilled without a distilation action.
that is water must be turned to vapor and allowed to condense over a separate container. and if im remembering my science correctly U sonic foggers dont actually use heat to create the fog.
if i remember correctly the ultrasonic vibrations at correct frequencies induce what they call cavitation, the heat is only a byproduct of the vibration caused by friction. anything thats water soluble and not killed by minute heat is carried to the roots
and yes a 60psi water pump can be a bit noisy, and yes plants can very readily absorbe water in various amount, but the purpose of the aeroponic setup is to give your roots the ideal conditions to grow giving an equal amount of water nute and o2 to every section of the root, and yes the results are phenomenal. this site is covered with grow journals of people doing aero.
and i agree with newgrowth, paint over them.
