Powdercoating Corto Radiators

I remember reading on here a year or so ago that if you have a radiator that has sections that are joined with threaded rods and machined metal nipples between each section, that the heat from powder coating damaging the nipples and making the radiators leaky should not be of concern.

So my question is, are American Radiator Corto radiators the type of radiators that are fabricated and assembled like the above or are they the ones that use the rubber or paper nipples that can be ruined by the heat of powder coating?

We refinished about half of our Cortos in the house 4 years ago by sandblasting and applying epoxy paint, but the paint finish was a little delicate and has sustained some chips. If I don't risk creating leaky radiators, I would prefer to powder coat the rest.

    Cortos use threaded nipples. I wouldn't powder-coat them.
