Why paint correction matters
Paint correction is the removal of a microscopically thin layer of lacquer to bring the surface back to level, which eliminates the swirls and light scratches that scatter light and make paint look flat. It is the only process that genuinely removes defects — polishes and glazes that "fill" them are temporary and wash out. It matters because clear coat is finite: correcting properly once, then maintaining the finish, uses far less of it than repeatedly polishing to hide damage that keeps returning. It is also the step that makes protection worth applying, since a coating locks in whatever condition the paint is in underneath it.
