One current soft wax gas check product (if available?!?) is CF Ventures wax wads/checks. They sound like dental wax sheets. Recently saw some postings on sheet wax for use as gas checks as well.
I recall years ago that there was a recommendation for using the sheets of pink dental wax. I found it on the net in soft, medium and hard wax.
Has anyone ever used the dental wax sheets as gas checks? If so, how did they work? With the high cost of conventional gas checks, this looks like a very cheap alternative if it works. Thoughts?
