there are many answers and it's hard to determine what is the best course of action. From your responses and what I can gather from all the old boats I've redone, it's apparent that even the manufacturers choose between the optimal way of doing something and what makes economic sense. Sometimes the effort and cost associated with doing something the very best way don't hold bring back the return it would take to make it all worth doing. I guess then it's just a matter of whether something bothers the owner of a boat enough to go to all the trouble to do something one hundred percent correctly or just "satisfactory and safe". I find myself starting every job wanting to do it the best way possible and almost every time compromising to come up with the way it's generally done as long as I think it's safe and has a reasonable shelf life. As I approach 70, "shelf life" is beginning to look differently as well.
