I got some resin inside the screw holes when I was installing the fusion plugs and now I can't back them out. Any suggestions?
Take a small drill (around 1/16" diameter) and carefully drill out the cured resin until a fin key can fit. Then back the screw out, it will pull the rest of the resin out with it. Take your time and make sure not to hit the finbox threads with the drillbit.
