Not sure if this is the right place for this, but here goes. I recently restarted my kettlebell practice. And after using some bells at a hotel gym (right? that was amazing, had them in 4k increments from 4-24), I've really come to see the deficiencies in my crappy old painted (very slippery paint) 16 and 24k bells. It's not a huge issue for the 16, but the 24 starts to feel a little loosy goosy towards the end of the last set of swings. Has anyone tried taking their bells to a powder coating service and have the old paint removed and then a proper powder coating applied? Or am I better off just buying new bells?
