Bar's Leaks Cooling System Sealer/Conditioner

I've used this product regularly since 1992 in my 1983 Toyota Celica that I still own, my 1986 Nissan Frontier SEV6 (sold in '01), and my 2001 Nissan Frontier V6SC (still own) for regular maintenance. At every cooling system fluid change roughly every 3yrs, a half bottle is added to the new Anti-freeze...never any problems.
