I was power washing the cooling fins on a couple of builds and they kept flying across the yard from the pressure and getting the whale spooge (heat sink compound) off them the easiest way I could think of so I decided to hold one with my bare hand while I used the other to pull the trigger.......... It deflected from the pressure and the 2800psi took the skin off the back of my hand, bled and stung.... I got a hell of a scar now.........................
