So, this might not be as actable for this industry, but I come from manufacturing. I worked at Bell Flight for a long while, and during that job, composite bonding, there's various types of adhesives, different things do different things. The type I needed for this particular part, we were out of, what we did have was expired, but we had another type, and the man who I worked with, who had been there for 15, 20 years, was like, just use this one. Well, I didn't know any better, and I was aware of that. So I went, and I found a quality engineer, and I went up to him, and I was like, look, I have this expired stuff, I have this stuff that's different, what should I use if either? You know, I'm being told this, I'm being told that, either way, I need to get this part out, what can I do that's safe, efficient, and that you will sign off on? And I'm really glad I didn't listen to my coworker, because he was very clear on the fact that the adhesive, the one he was recommending me use, was not structurally sound, and would have caused damage to not only the part, but if it had gone through inspections, it would have caused further problems down the line.
