For people who run tools how do you like to do butt joints? I’ve been trying the drywall doctors method of running the 10” box on each side and then filling it with a 12” for second coat but it hasn’t been working out, still seeing tape after second pass. The hang job is pretty bad in some areas so maybe that’s it… not sure if I need to adjust my flatboxes or what, any insight would be great
