    3. Demonstrate setting-up, (fluid needle, nozzle, and cap), adjusting, and testing spray gun using fluid, air and pattern control valves (HP-I)         
  5. Apply correct application of two-component finishing filler to minor surface imperfections
    1. Demonstrate dry sanding area to which two-component finishing filler has been applied (HP-I)
    2. Apply suitable metal treatment or primer in accordance with total product systems (HP-I)

  6. Choose suitable sealer to the area being refinished when sealing is needed or desirable  (HP-I)
    1. Demonstrate removal of dust from area to be refinished, including cracks or moldings of adjacent areas (HP-I)
    2. Demonstrate removing, with a tack rag, any dust or lint particles from the area to be refinished (HP-I)
    3. Apply final cleaning solution to area being refinished (HP-I)
    4. Demonstrate removal of nibs or imperfections from a sealer (HP-I)
  7. Determine appropriate spray techniques for the finish being applied (HP-I)
