Wet mag? At Irvine last year I watched a TFH team member spraying stuff on the props then some other stuff. Said he was looking for cracks.
Yes Bob, cracks are what I'm looking for.

We use crack detector on our prop, mainly because it stainless and can't be mag'd. Its great for in the field use, like a fuel hydro between rounds. You can get at Granger or Mc Master Carr.

That is not wet mag. Wet mag involves magnetizing the part and magnetic dust in a solution that the part is either dip in or it is sprayed on an the particles will adhere to the crack due to north/south at the crack, and are detectable under a black light. Dry mag is similar except it is dry power and it leave a white line that can harder to see if the crack is very short and thin.
