From cutting and one-step correction to final finishing.
Polishing a Restored Classic Car: Build a Finish Provenance Record
A restored car can combine original paint, older repairs and recently refinished parts. The polishing plan should follow those finishes rather than the age of the vehicle alone.

Map the available history
Ask which panels were refinished and what documentation exists. Record uncertain areas instead of filling gaps from memory or vehicle colour. Include trim and decorative finishes that may need protection or a separate process.
Agree the preservation goal
Discuss whether the customer wants an overall enhancement, correction of a specific repair or retention of an established appearance. A maximum-cut approach may conflict with the purpose of conserving an older finish. Use a prepared reference area to make the goal concrete.
Test each materially different finish
Do not extend one successful polishing result across panels with different histories without checking them. Keep test conditions, product identity and inspection method in the record. Confirm any product-specific readiness questions for recently refinished sections with the responsible repairer.
Deliver the history with the result
Document corrected and retained defects, excluded areas and the accepted process. Keep the record available for future maintenance. This helps the next detailer avoid treating a preserved original panel as if it were a recent, fully understood repair.
Frequently asked question
Does an older car always need a more aggressive compound?
No. Vehicle age is not a correction specification. Surface condition, finish history and the agreed preservation goal determine the appropriate trial.
