Definitions

  • the present invention relates to a method of surface treatment employing masking member(s) to protect part(s) of an article such as a car body from said surface treatment such as coating, plating, vacuum evaporation, phosphatizing, and the like.
  • said part(s) of said surface of said article may be covered and protected with said masking member(s).
  • said part(s) may be part(s) on which bracket(s), frame(s), and the like is(are) attached, and hole(s) such as water ejecting hole(s), harness hole(s) and the like.
  • a coating agent such as a polyvinylchloride-sol, a tar-urethane mixture and the like is effected on(in) said part(s) or said hole(s), in a case where said part(s) on which bracket(s), frame(s), and the like is(are) attached, it is difficult to attach firmly said bracket(s), frame(s), and the like to said part because of the coating layer formed by said coating, and in the case of said hole(s), the surface treatment leaks from said hole(s) to waste said coating agent and further it may be a concern that said coating agent fills in said hole(s) or stains the inside of said hole(s).
