After working the transport position for a while I became tired of getting my personal handcuffs mixed in with the office cuffs. A real PITA to sort through the mix of nickel plated handcuffs. I bought a pair of blued cuffs, but they are a pain to keep rust free (maybe because I use open top cases). Has anyone painted their nickel or stainless cuffs? I was thinking about maybe truck bed liner, so long as I masked off the hinges, holes, and ratchet area.
