It can chip,crack then moisture can get in between it and the metal and rust,much like undercoat,you have to repair any cracks,chips pronto.

I just knew somebody would ask that, that's why I didn't say anything more. 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. ![](/ubbthreads/images/graemlins/Twocents.gif)

Rust might be an issue where you live where your cars rot from the inside out but out here there is no difference between paint and powdercoat

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

As a general rule I don't like powder coating, it promotes corrosion.
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. ![](/ubbthreads/images/graemlins/Twocents.gif)

Ever watch the chopper show with junior? After they get a frame power coated the bolts won't fit the holes, so what do they do? 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
