Look, I am not trying to slam you, but you came in with an extremely detailed thread, on how to fix a rusty axle housing, and detailed a parts list and price tag WAY beyond what anyone else here that has dealt with this issue has paid. I don't want anyone coming here, reading your thread, and thinking that is their only option or the only safe option (not that it isn't a valid and quality solution). You linked that thread here, so I want the OP to know that he doesn't have to spend what you did, and do as much as you did. If money wasn't an issue for you, then in the words of Virgil Sollozzo, "te salud", but for me, 2k wasn't an option.
And for the record, the JB weld patch ins't a "smear and hope" solution. I never said it was permanent, but I think it is much better than a "smear and hope" band-aid. Multiple people have gone that route, and those that left it on long term got anywhere from 8 month to over a year and counting out of the patch.
I don't know your full situation, so I can't judge your decision to go the route you did, but my rig was my DD as well, and the fastest solution to keep me on the road was the JB weld patch. And that simple cheap patch allowed me to wait on the full swap until my schedule allowed, and I sourced parts at a much better price. Other guys have sourced parts way cheaper than even I got mine for, so in their cases, you are talking fixing the rust problem for 1/10th the cost of your fix. That is meaningful.
You also did some things that I straight up disagreed with, like stripping the stock coating off the axle and putting bedliner over it. I would never strip off an electro deposited coating (which the stock stuff probably is) and replace it with something I picked up at autozone for $30. The stock coating won't last forever (obviously) but I think it will last longer than anything you paint on. That's just my opinion though, maybe you have access to some much higher quality bedliner that the rest of us don't have easy access to.
