    If you go the 98% route needless to say you need to be effing careful with it, especially when mixing with water.
    Yea I only got chemical gloves and glasses. No HEV suit...

    Happy to just get the 33%.

  2. Hmmmm Not looking great...

    Ill leave it in the dye for 15 mins and come back.

  5. Just want to check.

    1L of 33% battery acid (I have 31-38%) mixed with 3L of water for 4.5asf?
