Rio Red (AC-424) Touch-Up Paint for Citroen

The Look

This color captures a very specific moment in French automotive history. It only appeared during the 1971 production year, which makes your car part of a small group that includes the early GS and the iconic 2CV. This is a deep, honest red that avoids the orange tones of later decades. Because your car has likely lived through many years of sun and road wear, the original paint might have lost some of its depth. You should expect this fresh pigment to look richer than the aged sections of your panels until you give the surrounding area a good polish.

Technical Details

This is a solid finish with no metallic flake or pearl additives to complicate the process. While solid colors are easier to match because you do not have to worry about the orientation of metal particles, red pigments are the first to fade when exposed to the elements. Since there is no flake to hide imperfections, the quality of your work depends entirely on your preparation. If the surface is not smooth, the gloss will highlight every ridge and dip. This paint has high opacity, so it covers well, but it requires a clean, oil-free surface to stay anchored.

Best Practices

Before you spray or dab Citroen Rio Red (check for code AC-424), you need to shake it for 60 seconds. You can find your paint code on a small, circular aluminum plate riveted to the firewall inside the engine bay or occasionally near the front wheel arch. To ensure the color is right for your specific car, always test the color on the included card and let it dry before comparing it to your panel. When applying the paint, keep the container moving to prevent the liquid from pooling or creating a heavy edge. Apply several thin layers rather than one thick one, and allow enough drying time between each pass so the surface remains level and firm. Work in a garage or a patch of shade to keep the surface temperature consistent while you work.
