Here is some advice for Vanagon mechanics from Grapes of Wrath:

"He strained and the wrench slipped.  A long gash appeared on the back of his hand.  The blood flowed evenly from the wound and dripped into the pan.  Hell, I never fixed no car in my life without cutting myself.  Now it's done I don't have to worry no more.

Well, I can stop that.  He urinated on the ground, picked up a handful of the resulting mud, and plastered it over the wound.  Best damn thing n the world to stop bleeding."

Maybe we can place this piece of advice in the archives?
