I've used that 5 min. epoxy before with not too good results.Super glue or a slow curing epoxy is the most durable.Flat rough surfaces that match well are the best.Some guys on here really do more articulate tips.Maybe others could pipe in,or you could do a search maybe.They are kind of a personal touch type thing.To get em nice,round,& bullet shaped I do the old shoe shine method with an emory cloth.
