I, along with most other responders to this question, agree that 5-min epoxy or other quick setting epoxies are only relegated to items that need or can be changed easily such as joint pins or ferrules. The glue is to soft and doesn't stick as well as other epoxies. When utilized as a base coat or a finish a bump against a hard object, to often will leave an oblique air pocket under the finish.
For years I used G-10 before finally deciding that it just never had a place in cue building.
Use what you wish and later learn from your experience as I have but after more than 50 years experience and heartbreaks I only use G-10 for quick, non permanent, applications.
