    OK, then. It's on me. You don't get rights of review. Straight up from my viewpoint.

    I'll post a new class report thread when I get it all together in my head. I have it on personal information that not just you but other women feel uncomfortable posting honest trip reports. This is a serious problem with this board.

    It was my great pleasure to dive with you. We drove 14 hours (two days each) from opposite directions. Neither of us regrets the time and effort. It is a shame that you feel hesitant to post your personal experience.

    I learned recently that there are some problems occurring in Insulated glass units that have silicon spacer bars. The aluminum spacer bars are not as efficient but the silicone spacers create an interaction with the low E coatings. When I told the forensics investigators what I've learned here about silicone and the release agents migrating back onto the glass when stored in a closed environment they got quite excited and will be investigating silicone migration from off gassing now. I will try putting the antifoam on the mask before storing it to see if that keeps the silicone deposition at bay.

    It may have nothing to do with release agents and may be the silicone frame doing the deposition.

    Ray,

    Interesting, but as I recall from when I was a productive member of society, Antifoam A likes to be in propylene glycol. I seriously considered it as a lens coating but backed off due to its issues.

    I'll be annoying Dow chem. tomorrow. Stay tuned...
