I used a commercial 2 part that I got at home depot. Had some color flecks that I didn't use. Made 5 gallons at a time only so I ended up letting everyone gallons harden in the pail unused. When mixing be careful as they can vary and it is hard to get the timing to box two things gallon pails. Have a third pail but you have to be fast. Having two people helps.
