i personally have not but my dad owns a power coating company.. i would recommend getting it dont in a PVC powder.. if your not familar with this type .. its what is used to make the handle grips on most channel lock pliers. this power is extremely durable but soft so you wont get any ding sounds from metal on metal contact. this is a soft powder so it can dent,but you would have to be very harsh with your setup to do so. if you have question about powder coating i can help been doing it since i was 14
