Polishing Compound Cost per Job: Look Beyond Bottle Price

The cheapest bottle is not necessarily the cheapest route to an accepted finish. A polishing system consumes liquid, pad capacity and labour. Evaluate those costs against the same service outcome rather than comparing container prices alone.

Measure actual liquid consumption

Use an appropriate consistent method to record product used on representative jobs. Note vehicle size, correction scope, stages and relevant conditions.

Do not treat one measurement as a universal millilitres-per-car rate. A light enhancement and substantial correction are different services.

Include the supporting work

Record pad use and cleaning, residue removal, detail cleanup and refinement. A fast cutting stage may create additional finishing labour, while another system may take longer initially but simplify completion.

Separate machine time from total technician time. Customers pay for the completed result, not only the minutes the pad is moving.

Use a transparent calculation

For an illustrative internal model, total consumable cost equals the liquid used at its unit cost, the allocated pad cost and other job-specific consumables. Add measured labour at the studio’s chosen costing rate.

Those inputs should come from the business’s own records. Do not copy a supplier’s best-case demo and present it as your guaranteed production cost.

Compare equivalent results

Use the same accepted finish standard and similar starting conditions. A lower-cost test that leaves substantially more defects is not an equal service.

Record rework as well as first-pass performance. Difficult wipe-off, inconsistent pads or repeated refinement can dominate small savings in product price.

A reliable purchasing decision uses several representative jobs and preserves the variation between them. The result should show where a system performs efficiently and where it needs a different process, not reduce every vehicle to an unsupported single cost figure.

An illustrative comparison

Suppose one process uses €4 of liquid and 90 minutes of labour, while another uses €7 of liquid and 60 minutes. At an illustrative labour cost of €30 per hour, those subtotals are €49 and €37 respectively. The dearer liquid can produce the lower process cost. These are example inputs, not market prices, and both processes must deliver the same accepted finish.

Add pad wear, towel laundering, refinement, preparation and rework before using the calculation in a real quotation.
