I just want to tell you what a great product your Super Coolant is!  I used to add Water Wetter to my 240Z's radiator, but everytime I changed the antifreeze I found a brown gunk. I've been using your Super Coolant for over a year now and the system is spotlessly clean -- and the car runs about 10 degrees cooler now.  I'm really glad I found your product and have already told both car clubs that I'm in about your product.

Great stuff!   from, Joe Shehan, Davenport, Iowa
