I have seen wood that has become 'pulpy' or 'rotted', after having the glycerin based product used. Mind you this was years ago, and had been used by previous tuners. I think the glycerin, keeps the moisture in the wood, not letting it release the moisture, resulting in the rot. I used to use Pin Tite, but it seemed to be a hit and miss situation. The article quoted is pre 1999, and would have little relevance in this discussion about C/A, which came after that article. Each to his own, C/A is for me, but obviously not for you. On a survey, I am sure C/A would win. C/A has never failed me.
