What should not be done when machine buffing a finish?

When machine buffing a finish, it's important to allow the buffer to do the work rather than applying excessive pressure. Pushing down on the buffing machine can lead to several issues, including uneven polishing, excessive heat generation, and an increased risk of damaging the surface being polished. Proper buffing technique involves maintaining a light touch and allowing the machine's weight and the pad's movement to effectively work on the finish.

Using a clean pad is essential, as it prevents contamination of the finish and ensures uniform application of the polishing compound. Additionally, applying the compound evenly helps achieve a consistent finish, while managing the buffer speed according to the specific material and desired outcome ensures optimum results. Each of these practices contributes to a successful and safe buffing process.
