AC-640 - Delta Blue Metallic Citroen Touch Up Paint

The Look

1974 was a massive year for your car, serving as the bridge between the legendary DS and the futuristic CX. This blue sits right in that sweet spot of history. It is a mid-tone metallic that gives the body lines a sharp, defined character without looking flashy. Since your Citroen has lived through several decades, the original paint might have darkened or faded, so expect a bit of a story when you start your touch-up.

Technical Details

This finish is a metallic, which means it relies on tiny flakes to reflect light and create depth. These flakes are heavy and love to sink to the bottom of the paint. If you do not keep the liquid mixed, you will end up with dark patches or stripes on the surface. This happens because the flakes clump together instead of laying flat. Maintaining a consistent flow and speed as you work is the only way to keep the finish even across the panel.

Best Practices

Look for your paint code on a small round metal disc riveted to the firewall or the suspension turret inside the engine bay. Before you spray or dab Citroen Delta Blue Metallic (check for code AC-640), you need to shake it for 60 seconds. This is the most important step for a metallic color because it wakes up those heavy flakes. Test the color on the included card to see how the metallic particles settle before you touch the car. Between layers, give it plenty of drying time in the garage so the next pass does not disturb the previous one. Keep the container moving at a steady pace to ensure the flakes spread out into a smooth shimmer.
