With the greatest respect to my fellow builders who may utilize it!!! The only uses Ive had for epoxy in the past 25 years as regards guitar making are: 1) Encapsulating electronics on occasion 2) Jigs and fixtures on occasion. Between a select group of aliphatics, hot hide glue, various cyanos, and a few other adhesives, my glue needs are complete sans epoxy. I must admit being raised to avoid it, what with my repair/restoration days. I have no need to fill in gaps, I have no fear of using water soluble glues in my neck making, and I have favorite ways of dealing with inlays sans epoxy. How about you all? Do you keep a fresh supply of epoxy on hand and if so, what do you use it for?
