Compound Grit Equivalents: Why a Liquid Is Not a Sandpaper Grade
Calling a compound 'equivalent to P3000' can confuse two different systems.
Compound Viscosity: Thick and Thin Do Not Rank Cutting Power
A thick compound is not automatically a strong cutter, and a fluid polish is not automatically gentle.
Compound Drying, Abrasive Breakdown and Paint Removal Are Different Events
Three events can occur during compounding: the liquid film changes, abrasive particles may change according to the formulation, and the paint surface is abraded.
Compound on a Damp Pad: Define Moisture Before Comparing Results
A pad described as 'damp' may contain very different amounts of water from one test to another.
Compound with a Pad Conditioner: Treat the Combination as a New System
A pad conditioner added to a compound changes the working combination.
Compound Residue and Inspection Solvent: Avoid a False Defect Diagnosis
An inspection cleaner can reveal compound residue, but an unsuitable cleaner or wiping method can also change the appearance being judged.
Compounding after a Break: Restart with a Clean Reference
After a meal break, overnight pause or interruption, the pad and panel may no longer be in the state that produced the accepted compounding result.
Changing Compound During a Job: Keep the Old and New Processes Traceable
Changing compound midway through a vehicle can be sensible when the original process does not suit a particular panel.
Compound Troubleshooting Log: Capture the First Failed Section
The first failed compounding section often contains the best evidence of what changed.
Compound Samples from Different Batches: Design a Fair Acceptance Check
Two bottles with the same product name but different batch identifiers can be compared through a practical acceptance check.

After microfiber cutting, the surface may contain a fine uniform pattern alongside a few original scratches.
