Personalizing or customizing gear for identification - anyone do it?

You can put initials on the bottom of fins and a mark of some sort on the front of your reg 2nd stage........

A deep wreck penetration guide I dove with in Truk was easy enough to follow into lower engine rooms, under boilers, etc...

I mark all my regs with a silver Sharpie on the exhaust t. All my dive buddies use gear that looks nearly identical, so having a name on EVERYTHING there really helps. Tanks and scoots have custom name stickers, small things are engraved.
