Paint Correction

A freshly painted classic car like the recently completed Buick Riviera by Matt Roehrock of MCA Customs can look excellent right out of the paint booth, but even the best paint jobs usually contain minor imperfections such as dust nibs, dirt particles, and orange peel (a textured surface resembling an orange's skin). Paint correction is the process of removing these imperfections to create the deep, glass-like finish seen on high-end show cars.

The key to a show-quality finish is surface flatness. When paint has texture or contaminants, light reflects unevenly, causing distorted reflections. By leveling the paint surface, reflections become sharper and clearer, giving the paint a deep, mirror-like appearance.

The process begins after the paint has cured according to the manufacturer's recommendations. The surface is carefully inspected under bright lighting to identify orange peel, dust nibs, runs, and other defects.

Next comes color sanding (wet sanding). Using progressively finer sandpaper—typically starting around 800 to 1500 grit and working up to 3000 grit or finer—the technician carefully levels the clear coat. The goal is to remove the tops of imperfections without sanding through the clear coat. Dust and dirt nibs are spot-sanded until the surface is uniformly smooth.

After sanding, the paint will appear dull and hazy. The gloss is restored through a multi-stage polishing process. First, a cutting compound removes sanding scratches. Then finer polishes are used to eliminate swirl marks and increase clarity. A final finishing polish, often called jeweling, maximizes gloss, depth, and reflection quality.

Many professional restorers apply extra clear-coat thickness specifically so there is enough material available for sanding and polishing, as Matt points out with seven coats applied to the Buick Riviera. This allows more aggressive leveling of orange peel while maintaining a safe amount of clear coat.

Paint correction requires skill and patience. Sanding too aggressively can burn through the clear coat, especially on edges and body lines. When performed correctly, however, the result is a perfectly leveled surface with exceptional depth, clarity, and shine.

In short, paint correction transforms a freshly painted classic car from simply shiny to truly show-worthy by removing dirt, dust, and orange peel and creating the smooth, reflective finish that enthusiasts describe as a “glass-like” appearance.
