cooling system flush

[prophecy]

anyone flushed their cooling system? I had a blown headgasket back in january that i fixed and i still havent flushed the system. Think it would probably be a good idea since I discovered the headgasket failure by the oil in the coolant res. Anyone have any recs on flush products to use? Ive heard of prestone and found this stuff RMI-25

the key thing is not always the products you use, but rather how well you do the job! :thumbu:
