Where can I find these ingerdients for Two Part?

Ok thanks.

I think the Kent calcium kind of defeats the purpose though. I could be wrong but I thought it was pricey...well relative to something like DowFlake.

I am really just looking to buy enough calcium (50lb. bag) and magnesium to make two part for a year. I guess three part if you add in the Mg

For the magnesium though, I don't mind using the kent product since its not used up as fast. I guess I will focus on finding the calcium then.

Anyone know of a place in or close to the city for DowFlake?
