I have powder coated my suspension parts in my garage with very good luck. I work in a tool and die shop, so I have access to a bead blaster and plenty of cleaning solvents. I'm not a pro, but trial and error have made me realize that prep is the key to it all. I had to rework some parts because I simply touched them with my bare hand after prepping them. Definitely must wear gloves and be careful of any type of contaminant. My car is driven regularly and I have not had any problems with any part that was powder coated. This includes almost everything from the K-frame to the rear end. I also used it to my steering column and some of the engine components.
