I'm not having problems with magnetization. I blew the rim off and wiped it down with denatured alcohol. The powder coat process wasn't as easy as I had hoped. It took me a while to get the gun lined out and even then it didn't flow to the part as well as expected. The finished product is pretty ugly. However, I did expect that result my first time and I learned a lot in the process. Thanks for all the feedback. You guys rock!
