Multi stage correction uses a sequence of machine polishing steps, each with different compounds and pads to progressively remove deeper defects and refine the surface to a flawless, high-gloss finish.
A standard detail or wax sits on top of the paint and masks defects temporarily. Paint correction physically removes a controlled amount of clear coat to eliminate the defects permanently.
It depends on the condition of your paint. A one-stage polish handles light swirls, a two-stage addresses moderate scratches and oxidation, and a full multi-stage correction is used for heavily defected or neglected paintwork.
When performed by a trained professional using the correct products and techniques, paint correction is completely safe.
Yes, always. Applying PPF or ceramic coating over defective paint permanently seals those defects in place. Correction first ensures your protection looks and performs exactly as it should.
The correction itself is permanent, those defects are gone. How long your paint stays in that condition depends on how the vehicle is washed and maintained going forward. Pairing correction with a protective coating significantly extends the result.
