Just finished wiring up and adding hooks to a batch for a swap on the other site. CCBC jointed striper pikie clones with a modified version of a Gary2 Smoky Joe paint scheme.
One that that I learnt with Systems 3 is that it really likes 70 degree or higher temps and low huminity. As with any epoxy, it doesn't like sharp edges as PM noted. I round edges at least a little with sandpaper, even on darters. Have used done the flip thing and the spinner thing. Both seem to work fine. Never tried the heater deal. Mix it well and evenly and keep above 70 degrees and you are fine. Its a little fussy otherwise.
Oh, and PM, its "Fixter"
