Pretreatment isn’t guesswork—it’s a discipline built on decisions made long before parts reach the finish line.

In this episode of Seen & Solved, Gary Raihl, Business Development Manager at Hubbard-Hall, shares how pretreatment systems should be evaluated from the ground up—looking beyond individual products to the full process. Drawing on decades of experience in powder coating and chemical processing, Gary explains why equipment design, chemistry selection, and operator ownership must all work together to deliver consistent results.

This episode covers:

• Assessing existing pretreatment systems based on stage count, process flow, and equipment condition

• Why tank materials, heat placement, and system design matter more than most realize

• Setting realistic performance goals and approval requirements before changes are made

• Balancing time, temperature, and concentration when real-world constraints exist

• Avoiding common mistakes that shorten equipment life and create downstream issues

• Training operators and using process control logs to maintain consistency and accountability

• Validating performance through testing and documentation—not assumptions

• The communication gaps between equipment, chemistry, and finishing partners that lead to the most expensive failures

Whether you’re bringing a new line online or working to improve control on an existing process, this episode takes a practical look at pretreatment as a system—not a single product choice—and what it takes to build a process that holds up in daily production.
