Okay, geoffkait, here are the links advertising Quicksilver Gold and a Positive Feedback review http://www.partsconnexion.com/cleaners_xtreme.html https://positive-feedback.com/Issue30/quicksilver_gold.htm
Apparently, it is almost the same as the Total Contact but had to be refrigerated and vacuum sealed after opening. It also did not sound good upon immediate application but took time to "gel." Total Contact sounded good immediately and Frank did not refrigerate or vacuum seal his syringe of emulsion. So, yes, QG was a bargain, but it is no longer available. The next better thing at higher expense is TC which is why I am buying it. I have not tried any other of the contact enhancer products. I am satisfied that TC will fill my needs with an ample supply for $300.
