Proper Approach? - CA pinblock repairs

[John Ross]

Hi Bill,
It is my understanding, that the glycerine treatment is a no no.
Apparently it works by the glycerine attracting, moisture. Over the years it
attracts more and more moisture, and you end up with rot.
Just what I heard, it may or not be true.
Regards,
John M. Ross
