PetesPonies Posted February 3, 2018 Share Posted February 3, 2018 I never used it, but know people who have. They liked it. It is a phosphoric based chemical, with some polymers added. I just use phosphoric acid. I talked with a DuPont Engineer in R&D once, in depth about Phosphoric acid and how to use it. I stick with it. It's easy to come by and you don't have to pay extra for some company's version :) Sent a can of Master Series to my best childhood friend yesterday. in Maryland. Was only $8 shipping, I was surprised. Link to comment Share on other sites More sharing options...
