I could see grease of any sort attracting dirt/crud and winding up back at square one (pads not sliding), though, so I'm thinking it's not wise to use, unless if necessary. OTOH grease would fix the rusting bit.
This is the stuff that Hyundai recommends:

For me, I use either 3M Silicone Paste or Motorcraft XG-3A on the slide pins, and Honda Molykote M77 paste for the metal-to-metal surfaces. The M77 is a dry-lube that would work excellent for the purposes that you described.
The CRC synthetic grease linked (not the red goo) I just found to be totally dried out and sticky in the rubber boots on rear of my Sequoia. Brakes are 2 years old. I actually had a VERY HARD time getting the caliper slide pins out. I just picked up Sil-Glyde and some of the new Permatex Ceramic counter packets. I might try one on each side to see how it works at next round/check up.
Hyundai and I'm sure have the TSB's that discuss filing the ears slightly before install. The paint/dirt/rust etc. makes it tight and they don't move correctly. Once they hang up the pads wear much faster.
