Heavy Cut Trial Reports: Separate Cut Rate, Haze and Paint Risk

A single overall score can hide the most important differences between heavy-cut systems. One combination may remove defects quickly but leave more haze; another may be easier to control but slower. A useful trial report keeps those outcomes separate.

Define three independent questions

Cut rate asks how quickly the selected defects improve under a specified process. Finish quality asks what the cleaned surface looks like after cutting and after any refinement. Paint risk asks whether the work is justified on the actual finish and geometry. The third cannot be reduced to a marketing score inferred from gloss.

Use matched areas and document the starting condition. Record the machine, pad, compound amount method, cycle definition and cleaning procedure. If any of those change, identify the change in the report.

Use a report with visible tradeoffs

| Report field | What to record |
| — | — |
| Target defects | Type and reference photographs |
| Cutting response | Improvement after a defined cycle |
| Residual pattern | Haze, isolated marks and uneven zones |
| Recovery stage | Process needed to meet final acceptance |
| Handling | Stability, wipe-off and pad maintenance |
| Limits | Excluded defects and uncertain paint history |

State whether a numerical value is a measurement, an operator rating or an illustrative calculation. A subjective five-point haze scale can be useful within a trained team, but it is not interchangeable with an instrument’s haze reading.

Report the whole result

Include failed or inconclusive areas and explain why they were excluded from a comparison. Removing every awkward result can make a weak process look reliable. If the starting defects were too different, report that the trial cannot support a ranking.

Do not convert a successful workshop test into a universal claim about all paint systems. Specify the conditions under which the combination was accepted and what must be retested on a new job.

The report should let another technician understand the choice, reproduce the key checks and recognise the limits. Heavy-cut selection improves when speed, finishing work and paint preservation remain visible as separate decisions.
