Hey, I ran out of the stuff in the green metal can. I had to juice up this central air conditioning system that says it needs R-something or other. Well, the green can ran dry. So I used some of the stuff from the other can. I used the last several pounds of 12 stuff in the white can, and then used some of the purple 502 stuff.
Seems to work OK, but the people are asking questions. Miss Manners wants to know. Am I a f'ing hack after all?
