Has anyone that was having pellet bridging/feeding issues tried doing anything to slick up the hopper? I've read that several other manufacturers (like Yoder) recommend using car wax on the hopper surfaces and polishing. I have also seen in some forums where folks have had luck putting down foil tape (like is used in HVAC applications). I'm curious if anyone has tried these with the Smokefires yet? Mine is coming tomorrow and I will probably try the wax idea.
