John,
Sorry I rambled on. It's fun finding new ways to do things. My Step-Fater is a Chemical engineer and agrees with both the Pro-Blend product "40 Below" with Deionized Water and a rust inhibitor and is even more impressed with the Evans product. I for one, living in Austin, TX where the weather is also over 100 degrees during the summer am going to go with the Evans. It also has no pressure associated with it and is good for 10 years and 100,000 miles !
Regards,
