Invisible Gloves...okay...they're invisible you can't see them. Actually it's a barrier cream for your skin. It protects against harsh chemicals such as MEK or Skydrol for up to four hours. It's a Mil-Spec product and highly recommended before handling anything harsher than water. By the way, it comes off with soap and water. Perfect product for working on greasy or carbon covered pieces also. Buy one for the hangar and one for the garage!
