Use at your own risk, add the components in the provided order, always remember the acids should be added slowly to the rest of the mix while agitating. The distilled water could be deionized water. PEG could be 3350 up to 8000 molecular mass (g/mol) for more info check this abstract: Influence of Molecular Weight of Polyethylene Glycol on Microvia Filling by Copper Electroplating. If using 35 oz. CuSO4/gal solution it's concentration is 14.637%
