Paint Correction Stages Explained

Single polishing pass with a fine cut polish. Removes light swirl marks, very light water spots, and surface haze.

Time: 4 to 6 hours on a sedan.

Best for: newer cars (under 2 years), cars that have only seen hand washes, cars that already look pretty good and just need a refresh before sealing or coating.

Result: paint looks fresh and even. Won't remove deeper scratches or oxidation.

Two-step process. First pass with a cutting compound to remove deeper swirls and lighter scratches. Second pass with a refining polish to remove the haze left by the cutting compound.

Time: 6 to 10 hours on a sedan.

Best for: 2 to 5 year old daily drivers, cars that have been tunnel-washed or improperly hand-washed, cars that show heavy swirling under direct sunlight.

Result: dramatic improvement. Paint depth and gloss are restored. Most defects gone, some deepest scratches may remain.

Three-step process. Heavy cutting compound, refining polish, final finishing polish. Removes deeper scratches, oxidation, severe swirling, and most of what a daily driver has accumulated over the years.

Time: 8 to 16 hours, often spread over two days.

Best for: 5+ year old cars, neglected paint, cars being prepped for ceramic coating, dark-color cars where Stage 2 isn't enough.

Result: paint looks correction-grade. Deep, wet, even finish. The car looks like a different vehicle.

Look at the paint under direct sunlight or with a flashlight at an angle. Swirl marks look like spider webs. Scratches show as lines.

Faint cobwebbing visible only at certain angles: Stage 1 is enough.

Visible swirling under most light conditions: Stage 2.

Heavy swirling, dulled paint, visible scratches at multiple angles: Stage 3.

Clear coat that's peeling, oxidized to white, or failed: correction won't fix this. The paint needs to be respray.

Every stage removes a small amount of clear coat - usually 2 to 5 microns per pass. Modern clear coats are 40 to 60 microns thick.

Stage 3 on a car that only needed Stage 1 wastes 6-10 microns of clear coat for no reason. Do that twice in the car's life and you've removed a significant portion of the clear coat with nothing to show for it.

A real detailer measures the paint with a thickness gauge before deciding the stage, and stops when the defects are gone instead of grinding to a finish.

Rock chips. Those go through the clear into the base coat or primer. Correction doesn't touch them. Touch-up paint or paintless dent repair handles those.

Deep scratches that have caught a fingernail. Correction can shallow them out but rarely eliminate them entirely.

Clear coat failure. Once clear has peeled or oxidized to the point of failure, no polish brings it back.

Paint that's been previously over-polished. If a body shop or previous detailer already cut too much clear, there's nothing left to work with.
