Don't take it all personally. It's a forum and everyone here has their own views based on their experiences. And of course - hindsight is 20/20. When you're pissed off and seeing red for being in a crappy situation, it's just easy think you were set up. We've all been there, but lucky for you - You've got us to give it to you straight.
MOPAR accessories aren't any better than anything else. Dealerships tell their customers to buy whatever products they sell because of this or that, when in actuality its no difference than any other product. It's just business.
Personally, I don't use anti seize on my bolts, but that is because I live in Arizona. If I lived in a climate of extreme cold, rain, mud, etc. I would use anti seize. I think wheel companies avoid this question because of liability, and they just give basic install instructions, if any, and are very clear that beadlocks are for off-road use only.
I'm by no means a professional, this is just my hobby, but one thing I know to be absolutely true is that no one is going to give your jeep the time, and attention to detail then you. Not the classy fabricator churning out $200K custom buggies, and certainly not the techs at a dealership. It's just not going to happen. Always check it over yourself.
