I have been reliably informed it stings even more when you get Skydrol or Exxon Hyjet on your wedding tackle!
Indeed it does! Over many years of working on with hydraulic systems, I was fortunate enough to never get any sprayed on me...but a Skydrol mist is horrible, gets in your throat and eyes and you cannot do anything but get out of the way.
If you wash NEARLY all of the Skydrol off your hands and then go to the Men's room, the residual fluid on your hands gives a warm glow to your bits.....
.....quite pleasant really!
