Designed to quickly eliminate leaks of antifreeze from the cooling systems of cars and trucks of all brands. Compatible with all types of antifreezes. Adapted to radiators and interior heaters of any designs, including those with "flat" tubes. Does not affect the performance of antifreeze, which after applying the composition is not required to be changed. It is polymerized only in the leakage zone due to the active evaporation of individual components of the drug. By circulating in the cooling system, it automatically eliminates new leaks.
