Abstract
In a method for applying a protective coating to the rod section of a sucker rod having upset ends, one or more resilient cylindrical protective sleeves with longitudinal slits are spread open and urged by radial force over and around the rod portion of the sucker rod. Using an appropriate fusing apparatus, the edges of the protective sleeves' longitudinal slits are then fused together, and adjacent sleeve ends are circumferentially fused together.
