NOVOL 1K ACRYLIC PUTTY 100ML1K one-component acrylic putty is a finishing putty. Its main purpose is to fill very small scratches and surface defects directly before coating. The product is coat able with all acrylic and base products. Hence it must be applied in very thin layers and left for the solvent to flash off between the successive putty layers and sanded with the same abrasive papers as acrylic fillers.
