5. use silicon plugs to plug off any holes, threads or bearing races
6. bake metal to temp to outgas metal and get oils off metal from hands or prepwork only cast metals need to be outgassed and an ordinary curing oven wont get parts hot enough to burn off oil, finger oils shouldnt be present to begin with. (poor material handling)
7. use hi temp tape to cover anything you dont want coated -powdercoat items
8. bake powder to scheduled temp/time
9. apply clear and bake again orelse its done if no clear is needed.
You can get powdercoating supplies just about anywhere.
example: harbor freight... <------- Gaaaaaaaaarbage
The place you take it to get coated will probably have the silicon plugs and hi temp tape.
Have them cover your vin with hi temp tape before they coat it as well. lol.... amateurs.... a nice making tape skid mark over the vin is always attractive!
Hope that helps....

I'm not trying rag on anyone, too many people have been misinformed on this process thanks to companies like Eastwood, Columbia coatings, powder by the pound.... they dont care if its done right, all they care about is selling to the consumer that doesnt know any better. They draw people in with the "do it yourself and save money" bullshit. They also dont tell you critical information like the importance of proper media blasting and what it costs to get setup to media blast in a timely fashion. I leaned the hard way. I blasted 2 frames with a small harbor freight blast pot, took each one 6 hours to blast with a 40lb pot and 12.6 CFM air compressor that cost me $950. The blast room I use now would cost someone $100,000 easy and that same frame I could fully blast in about 15 minutes. The frames were machine frames and just needed the pickling/mill scale blasted off, thank god there was nothing more! I would have shot myself if it took any longer. Most of that time was not blast time but was refilling the 40lb pot. Took longer to empty it out. PROPER chemical treatment is also important along with blasting to meet ASTM B117-09 testing.
