A full polishing range.
From cutting and one-step correction to final finishing.
Use a fixed vehicle inspection route with explicit lower-panel checks to catch missed coating residue and coverage concerns before handover.
Updated · NANOLAB Knowledge

Upper panels attract attention because they are easy to see under workshop lights. Lower doors, sills and complex bumper areas are easier to miss. A fixed inspection route makes coverage of the inspection itself visible.
Do not assume that an area was accepted because it appears on the application map. Inspect the completed work with a separate checklist. Record exclusions so an intentionally untreated surface is not confused with an omission.
| Pass | Focus |
|---|---|
| Overall walkaround | Uniform appearance and obvious concerns |
| Upper and middle panels | Reflections, boundaries and local residue |
| Lower panels | Sills, lower doors and bumper contours |
| Interfaces | Trim, badges, film edges and agreed exclusions |
Arrange suitable lighting and safe access. Do not adopt unstable positions or use vehicle lifting equipment without the appropriate competence and procedures. The inspection plan must fit safe workshop practice.
Use a vehicle diagram or photographs rather than touching the fresh surface. A note such as “left rear lower door, forward edge” is more useful than “some haze on the side.” Assign each concern a status: accepted, corrected and rechecked, or held for review.
A local correction can transfer residue into an adjacent area. Review the corrected zone and its boundaries under the relevant lighting. Do not close the checklist merely because a towel was passed over the marked spot.
In an illustrative handover, a lower sill shows residue only under an oblique light. The route catches it before delivery even though the main door reflection looked excellent. That is the practical value of checking difficult areas deliberately.
Record the inspector, time, unresolved limitations and release conditions. Where two people perform the work, the final reviewer should use the record rather than relying solely on verbal reassurance.
A consistent route does not guarantee perfection, but it makes missed areas less dependent on memory and gives the workshop a repeatable standard for every job.
