I think a few clarifications may be in order:
*) The most common method of using micromesh with water is more of a slurry than flushing action. Elimination of this may be in order. This is one of the big reasons why buffing became popular. However the buffing compound itself can also be a source of moisture induction.
*) 'Accelerator' is more often than not acetone, check the MSDS, I have said a number of times how bad acetone is when dealing with CA. That might be a topic for another thread. Accelerator by itself does not cause cloudy spots unless it has water, H2O in it. Accelerator is nothing more than a neutral PH chemical that causes the PH shift in the CA thus neutralizing the very weak acid stabilizer and causing the CA to polymerize. To those who have seen bloom with use of accelerator can you please state, or PM me, which accelerators you were using and how much?
*) Cloudy, referred to as bloom, is the reason that CA fumes is used to detect fingerprints, that is directly related to moisture. Moisture, water, H2O is the key. Even when you seal up the ends of the blanks with CA moisture can still get in there. This equates to the home and hydrostatic pressure in the building materials.
*) Cloudy can also be separation of the blank material to the CA finish. Be it due to material shifting, foreign materials inhibiting the CA from bonding to the material (i.e. wax) or the like. The look is drastically different between the two and once you see the difference it becomes very obvious.
Consider this. If you take your nonstabilized wood pen with CA on to a drastic different moisture environment (high MC city to low MC desert for example) there will be a shift in the wood moisture content. This shift will cause the CA finish to MOVE. If your CA is hard, rigid and non-flexible then it can CRACK. Reactive materials, antler, horn, bone, wood just to name a few, should have special considerations when you work with them, i.e. location, storage, handling, usage.
