I understand the ends needs to be masked off so they fit in the control arms and frame. Thanks Nicklas

Then you get into physical property variables or paint vs powder coating. I don't like the thick, gloppy, and usually overly glossy look of powder coating, especially on a restoration.

Paint is chemically bonded to clean metal, and powder coat is just plastic powder that is heated and melted. It's just laying there. If you have to do anything after powder coating something, like say ream a hole back to size cause the bolt won't fit anymore you have broken the seal, or sand the ends of the T bar the seal is broken, and moisture will wick up under it. In Alaska they had bush planes that had tube fuselages that looked ok, but upon inspection they found that most of a tube has rusted away under the powder, and it still looked ok. Some lawn mower companies have quit using it on the mower decks for the same reason. It's ok on certain stuff, like my Hemi valve covers, but that is not K frames, T bars, or structural parts.

How many torsion bars have you seen rusted to unserviceable? And with the caliber of cars being fixed up, are they going to see much salt or corrosion sitting in the garage or at the local car show.

The powdercoating industry has addressed those issues the last few years, assorted primers and rust preventive bases are/can be added before a part is powdercoated... FYI I generally prefer to dip the torsion bars (after derusting/stipping) in POR-15 Chassis Black and let them drip dry horizontally for a factory appearance

Did a thought cross your mind that maybe your powdercoater skips a few important steps in the process? Properly done powdercoating should not chip,peel or crack.

Take a drill bit and ream it, which brakes the seal.I was just saying it's ok on certain stuff. I don't have a personal powder coater,cause like I said, as a rule I don't like it. To the OP have the TBs coated, and if they put to much on the ends, and they won't fit in the sockets, then what? Grind it off? Then you just broke the seal.

The bars could be treated with an acid etch-ant high temp primer for corrosion resistance, the hex end can be "taped" off during the powder coat application, good communication to the coater as to your intended usage/application from the end user goes a long way in achieving the desired results/benefits

I paint most things myself at my convenience. The finish is great. I can mask what I don't want covered. If it ever chips I can touch it up or redo it. And a good prep, epoxy prime and single stage is a pretty good coating. As for the comments about "breaking the seal" - well, that will happen with just about any coating with any thickness ... unavoidable.
