Before using, fillers need to be reconstituted by pre-mixing Part A thoroughly. The best method is to use a “Turbine” mixer (available from Smooth-On) or similar drill mixer attached to a power drill and drill mix on medium speed for 2 minutes. Follow with hand mixing using a flat edge paddle for 1 minute until fillers are uniformly dispersed.
