The DERMAUTOLOGY EXTRAFILLER PRIMER 4:1 WHITE is the professional choice from DS COLOR to finalize the surface preparation stage in the body shop. This high-build 2K primer/filler is essential to ensure the success of the final finish, providing an ideal combination of filling capacity and support. Its formulation guarantees maximum adhesion on both bare metal and polyester putty, effectively insulating the surface before applying the color coat.

One of its most valued features is its performance as a foundation paint. The primer/filler fulfils critical functions such as: providing anti-rust protection, smoothing out sanding marks or porous areas to grant surface regularity, and acting as an insulator between the previous layers and the topcoat. Thanks to its "extrafiller" nature and excellent sanding properties, professionals achieve perfect flatness and optimize working times.

Furthermore, the WHITE color is crucial for tonal adjustment, improving coverage and color strength for light-colored finishes. To guarantee the correct drying and hardness properties, it must be used with the DERMAUTOLOGY HARDENER for EXTRAFILLER PRIMER.
