Paint polishing & correction
Clear coat anatomy, abrasives, machines, and correction protocol — from gloss physics to Panel Prep before ceramic.

Paint as a multi-layer system
A modern automotive finish is not a single “color coat” but a stack of defined layers. Each has a different function and different durability — which fundamentally changes how you can (and cannot) work on it during corre

Gloss is physics, not marketing
The feeling of “deep” or “wet” paint is not subjective illusion. It is a measurable interaction between incident light and surface topography — and machine polishing works because it microscopically levels that topograph

Two worlds of machine kinematics
Choosing a polisher is not about brand or color. Pad kinematics — how the disc actually moves on paint — determines how much heat builds at a point, what marks remain, and how much margin you have for error.

Three variables, one system
Machine correction is not controlled “pad speed” or “hand strength” alone. It is a dynamic system of three coupled variables:

What actually happens inside the compound
Polishing compound is a chemo-mechanical suspension: hard particles (abrasives) dispersed in a carrier (oils, lubricants, surfactants). Abrasive architecture — size, shape, and behavior under pressure — defines how cutti

Three compounds, full spectrum
FEYNLAB® A-Series is a three-step polishing system built on ceramic aluminum oxide with linear cut (see [DAT vs. SMAT](/edukace/abraziva-dat-vs-smat)). It covers the full defect range — from industrial oxidation to final

How-to guide
The pad changes how the compound behaves
The same compound on three different pads produces three different outcomes. Pad material, cell density, and fiber length radically change pressure distribution, heat rejection, and cut aggression.

When the polisher starts to squeal
The tech places a DA on the panel, starts it — and instead of smooth glide the pad hops aggressively, emits high-frequency squeal, and compound instantly cakes on the surface. Wipe-down with a microfiber leaves fresh scr

The last step everything depends on
Ceramic coating application requires a chemically clean surface at the molecular level. Not “looks clean,” not “washed clean” — exposed clear coat with free hydroxyl groups (-OH) for silicon precursors to form covalent s

Application protocol
Three phases, not three random compounds
Professional paint correction is not “spread and buff.” It is a three-step hierarchical process with a defined goal per phase. Skip a phase and its problems transfer to the next step — or directly to ceramic coating, whi
