The activator solution is unnecessary for hardening and probably best
if not used. (Activator is a pH buffer to bring the glut pH to about
8, where glut is most effective as a biocide. The pH of the stock
solution is about 4, at that point hardening is slower than at 8, but
fast enough for hand coating applications. Also, pH of 4 is much less
likely to interfare with iron based and dichromate processes.)
MaxiCide 2.5% glut without activator is the solution Chris has been
using.
