Buying Guide
Key purchase considerations
Choosing the right glass polishing compound depends on the type and severity of the glass imperfection, as well as the polishing method you prefer. Cerium oxide-based formulas are common for light to moderate defects, offering a balance of cutting power and clarity. Consider whether you mainly treat automotive glass, household windows, or both, as some products perform better on certain surfaces. Pad compatibility, tool requirements, and working time are also important to ensure a smooth process and a streak-free finish.
