How Much Paint Correction Is Sensible?
Correction should improve the finish while preserving the paint system. Polishing removes material, so a deep defect is not automatically a target for complete removal. A responsible plan considers previous work, panel condition and the result of inspection or a test area before deciding how far to go.

Share the paint history
Previous polishing, repainting and repairs can change what is appropriate on a panel. Tell the shop what you know and acknowledge what you do not. A car with unknown history should not receive an aggressive recommendation merely because a scratch looks removable in a photograph.
Understand the limits of measurements
Inspection tools and paint-thickness readings can help inform a professional assessment, but they are not a universal permission slip to polish. Substrates and paint systems vary, and a total reading does not always isolate clear-coat thickness. Ask how the available evidence supports the proposed process rather than asking for a single safe number.
Agree on acceptable remaining defects
Choose the balance between improved clarity and preserving material for the future. A test area can help make this decision concrete. The shop should explain which marks may remain, why they remain and whether another service would address them more appropriately. A realistic finish target protects against unnecessary repeated correction.
Your decision checklist
Light widespread marring
Conservative refinement may help
Ask: What does the test area show?
Deep isolated defect
Removal may require too much material
Ask: Can its appearance be softened instead?
Failing or uncertain paint
Further assessment or repair may be needed
Ask: Is correction appropriate at all?
