Re: Loctite for reciever/barrel
Wow. I know this isn't what you're asking, and perhaps I am "asking for a blasting" here, but.... when I choose who I am going to have do *any* sort of work [custom or otherwise] for me, I try to go with someone whom I consider to be an expert - or at least knows more than I do. From there, I figure I am paying a premium price for that expertise I don't possess myself or find in someone else. Then I make it a practice to LISTEN to what that expert tells me.
On the other hand, I do consultant work and sometimes it costs me business, but I don't subscribe to the adage that the customer is *always* right. Especially where technical details are concerned. There are times when I advise folks on what I think is best, and if they simply MUST do it differently, I gently ask if they know more than I do, why come to me in the first place? I then refer them to someone who will do things their way.
Give him the benefit of your expertise. Offer your professional advice, and be sure to take the time to explain to him WHY you have this opinion. Then, if he insists he knows more than you, either:
A) let him specify exactly what he wants, with the understanding that you don't recommend/take responsibility for it or;
B) send him down the road.
That said, I bought a rifle (from a member here) with a brake locktited on with red locktite. A little heat from a propane torch and it came right off. No damage to the finish or anything.
