Hi all, I started glue sizing my spruce patches after reading "A New Look at Patch Fitting" by Joseph Grubaugh and Sigrun Seifert. The article mentions it in passing: "When the fit is nearly perfect, it may be desirable to glue-size the patch, at least on the end grain."
I can't think of a reason to not glue-size, except for the extra time and effort. Am I missing something? Any interesting takes on when glue-sizing a patch is critical and when it should be avoided?
