How much powder do you use? Reason I ask is my Spiceguy carries citric acid, and I bet he has a decent price too. Is it pure citric acid, or are there other "things" in there?
...just wondering while I wait for the return of my 300.
That reminds me...the other day I noticed a dark red, somewhat sticky substance on the engine side of the radiator....could this be watter wetter seeping through a before unknown pinhole? Or is it the remains of some juicy florida bug?
thanks for your indulgence!
