I used DMCMW's plating service a few times and it's great. Last year I did a full suspension refurbishment and sent them all my large suspension bolts, brackets, calipers, etc and it all came back great. Another option for hardware is to simply replace it. You'll go broke and empty handed trying to buy the right stuff at Lowes but if you go to belmetric.com you can order onesy-twosy of damn near anything you need and the price is GREAT, everything is zip locked by size/type, and they have a variety of finishes for most items. I'm doing a frame-off right now and I'm replacing most nuts, bolts, washers, etc. This is probably easier and cheaper for anything smaller than M12 compared to sending it out for cleaning and plating. I also opted to upgrade most 8.8 hardware to hardened 10.9 for not much more. Highly recommend these guys. In fact I think I learned about them from Mark W haha. First picture is my last haul from DMCMW's plating and the second picture is my most recent box of hardware from belmetric.
