I've been thinking about using thermocure on my 60. I've noticed rust in my coolant. It's not milky suggesting coolant mixed with oil. I haven't seen any scary reviews...just really good reviews. Can you share some of the scary reviews you found? Have you tried the Thermocure since you posted on Monday?I also picked up a couple of these. Thermocure
Going to run it with distilled water for a few days as well as the prestone stuff (not at the same time). Seems promising.
EDIT: Some of the reviews for the Thermocure are scary!!! Eep!! Anyone ever use this stuff?
