A full polishing range.
From cutting and one-step correction to final finishing.
Separating Compound Cut from Pad Footprint in a Test Spot
A wider polished area can look like faster correction even when the local defect reduction is unchanged. Compare pad footprint and cutting performance separately.

Assess the starting condition
Mark equal inspection windows inside two test areas. Keep the surrounding paint available as a reference. A larger pad may cover more paint per movement, but curves, access and the chosen machine can change its effective contact.
A practical working method
- Choose windows with comparable defects and prepare both identically.
- Record pad diameter, machine type and the completed working cycle.
- Inspect inside the marked windows after residue removal, then measure the total accepted area.
- Report defect improvement and area completed as two results.
Common mistake
Timing only the machine movement ignores pad changes, cleaning and inspection. Conversely, a narrow test window cannot describe the productivity of a whole bonnet.
What a useful result looks like
Use the results to choose a workshop process, not a universal ranking of pad sizes. Retest on representative contours before quoting a full-vehicle time saving.
