OK...well maybe "hype" was the wrong word to use for manufacture instructions, though often those CAN at times be full of hype in order to allow the manufacture to sell more product, eh??
That being said, and though you don't know me at all, I am in fact a competent mechanic with a fair bit of admittedly self learned, but also extensive wrenching skills. I work on all my vehicles, which include an old diesel bulldozer, a diesel loader backhoe, a gas 4x4 forklift, a diesel Jeep 4x4, a Toyota 4x4 pick up that I convert to a flatbed ranch truck, and of course my real fetish, an awesome 2005 Cummins powered Dodge Ram 4x4 truck fairly well modified. I also own run a small but thorough woodoworking shop FULL of vibrating machinery that always needs maintenance and sometimes repairs.
And from my experience(s), I can HONESTLY say that I ONLY use RED Loctite (despite maufaturesr suggestions otherwise) and I have NEVER had ANY problem removing a fastener later using ONLY torque and ZERO "required" heat.
Now, like I said, maybe I am applying it wrong, but I say this mostly in jest as in fact I DO understand the importance of using ANY type of fasteners ONLY on clean surfaces. If the threaded parts I am working on are at all dirty or oily, I properly clean them (both male an female) with appropriate brushes and/or swabs and often est Acetone as a solvent as it is an extremely effective and fast drying solvent!!! I then apply the correct amount of RED loctite, wait a minute or so, and then tighten the fastenr. If there is something wrong with my technique, then I really don't know what it is.
So here is an interesting idea for you... why don't you try it yourself on a brand new regular 1/2" fastener of your choice placed in your vise (rather then something important on your truck.) After properly cleaning the fastener and applying RED loctite per manufacturers instructions, try to loosen the fastener, say after a week or?? If you CANNOT remove the fastener a week later with out adding heat, then post back here, or PM me, and I'll gladly send you $20 PayPal or cash for your expense, trouble and efforts to do the test.
If you CAN in fact remove the fastener WITHOUT heat, and without undue stress on your vice or wrench or arm, then just post back here and we'll be even and you'll have some red Loctite that you can use whenever and wherever YOU think you might want and/or need to instead of simply following manufacturers reccomendations.
Maybe we can BOTH learn something that we already think we know, eh??
