The defect on the windowsill must be treated with a cleaner. The substance has a pungent odor, so it is important to ensure good ventilation. Cosmofen does not just clean the surface, but slightly softens the PVC, thus providing super-strong adhesion of the liquid plastic. It is important to use only a white rag so as not to stain the window sill with its dye.
