The vast majority of regs are chrome plated brass. Brass when exposed to salt water will corrode. That is can be seen by the blue/green build up. If your reg has a dent in it more than likely the bond between the brass and chrome has been compromised and as such water will intrude thus lead to corrosion.

Dent or not your best bet to prevent corrosion is to rinse and dry well.
 
Yes, you are right, the regulator (apeks fsr) is chromed brass and the brass is visible in the dent ("golden colour").
No way to repair it right?

Short of re-chroming not really. One could put clear fingernail polish on the spot. But at this point I would just rinse and dry well.
