The question for the January/February edition of PC Pop Quiz, along with the answer is:

Q: What is the recommended process sequence for a five-stage spray line in an iron phosphate application?

1. Water rinse, alkaline clean, water rinse, next generation conversion coating, DI/RO water rinse
2. Water rinse, water rinse, alkaline clean, DI/RO water rinse, next generation conversion coating

4. Alkaline clean, water rinse, water rinse, next generation conversion coating, DI/RO water rinse
5. Next generation conversion coating, water rinse, DI/RO water rinse, alkaline clean, water rinse

A: The answer is: Had we worded that question correctly, i.e., What is a recommended process sequence for next generation pretreatments, similar to the five stage spray line used in an iron phosphate application?, the answer would have been #4: alkaline clean, water rinse, water rinse, next generation conversation coating, and Di/RO water rinse.

Some of our readers astutely recognized the error and pointed it out to us. We are congratulating those who answered #4, but selecting a winner from those who caught our mistake. The winner is:

Ted F. Duda, Therma-Tron-X, Inc., Sales Engineering, Huntley, IL. The t-shirt you selected is on its way.
