Liquid and Sprayable PPF Does It Work? Dealing With Rust, DI Water and More. Episode #970

Liquid PPF is being marketed as the next revolution in paint protection—but does it actually do the one job PPF exists to do?Marshall and Nick cut through the hype surrounding liquid and sprayable PPF, explain why impact resistance remains the defining benefit of traditional paint protection film, and discuss how overpromising can damage both customer trust and a detailing business’s reputation.

They also answer real-world questions from the detailing community, including whether DI water is essential, how to approach rust on older vehicles, removing wax and polish from exterior plastic, safely cleaning biological growth from carpet, washing a freshly coated vehicle during love bug season, and using Stack as a value-added service for PPF and coating customers.

The episode’s central lesson is simple: if a product does not solve the actual problem, it is not a solution—it is a liability disguised as innovation.

Whether you run a detailing business, install PPF, apply coatings, or want to make smarter product decisions, this episode offers practical guidance grounded in real shop experience.
