Thanks guys,

I just got a hydrometer and have the same formula/equation, the only thing I'm missing is the MW of the gum which I need to find the SG??? I do know that keriks formula is the same ratio I've been using myself and awfully close to 14 baume and I'll start there. And will proly use the Benzoate rather than the Methylparaben because the benzoate has proven its self.

Once again thanks everyone.

Happy Days
