I went to the local salon supply store and picked up a gallon jug of Volume 20 Clear Developer for $6. I filled the bucket with hot water to dissolve the Oxy. As far as the Oxy goes, I didn't really measure it out. I just sprinkled it over the top, 3 passes the length of the bucket. I then poured in about a quarter gallon of the peroxide.

If you saw my writeup on the 128K Mac, I filled that huge rubbermaid tote up with hot water and poured in a half gallon of peroxide. Same with the Oxy, 3 passes back and forth over the top.
