Thanks for beating down the epoxy plan with experience and insights Diseasal and MxFrank. I'll get new. But I wanted to ask about the G-05. I checked my coolants found a full jug of Zerex G-05 and a partial jug of MB Antifreeze that does not mention G-05 anywhere on the label. Coolant in the car now is probably 4 yrs old. So probably a good time to X-change. I'm pretty sure the current coolant is the more expensive MB. Are you guys recommending the G-05 as the preferred blend or are they "the same ingredients"?
