Thanks for the useful feedback - all APPRECIATED and NOTED. In point of fact, I have read through a goodly portion of that thread and many others but found no specific mention - at least not one I would recognize as a layman on the topic of corrosion protection. Thus, my question...
does having another multipage page thread just to promote a USELESS item or answer basic questions AGAIN... serve a purpose?
Well, I wasn't aware we were trying to conserve electrons around here, and I certainly wasn't promoting ANYTHING. This is a forum after all, where topical matters can and should be proposed to a community without too much constraint. Otherwise, what use in providing a forum? It's up to members to choose whether to consume, respond or ignore as suits their particular desires.
Furthermore, I would argue that there is often merit in splitting threads versus lumping all related discussions under one "super thread". It provides a more discrete packet of information to consume, and gives much higher resolution for the limited .phpp search tools to operate on.
