Welcome back. Clean & rinse the wheel with a very light mixture of dish soap & water to remove any finger prints or sandpaper residue OR if you have some automotive grease & wax remover, that's what I use. Let it dry good. For the next step I suggest that you get a 1X2X6 wood strip and drill a 1/2 inch hole towards the top so you can mount the wheel. I used a rear lower shock bolt with 5 washers and it worked perfectly,(see photos) Next get a good quality primer. I use a SEM high build primer (photo 763) Give the wheel another wipe down and spray the primer with at least 3 coats with a flash time of 5 minutes between each coat depending on the temperature. let it dry overnight. Next, lightly wet sand the entire wheel with 400 wet (black) sand paper OR the equivalent Scotch Brite pad. This step should bring out your high & low spots and fill in pinholes depending on your primer. (photo753) repeat the mentioned steps until you are satisfied with your work... Then give it one last sanding with the 400 grit & clean
Now you are ready to move on to the color coat.. You can have a color mixed and put into a spray can by your local auto body supply, but it's not going to be cheap, but that's up to you. My wheel is going on the Code Z GS, the interior is black so I picked a stock High Gloss Black from Krylon.(photo 776) It's less than $10 a can and if I want to touch-up the wheel It's an easy fix. Pick a nice warm day and let the paint can sit in the sun OR place the can in a bucket of warm water. Warm paint will spray better and give you a nicer finish. At least 3 coats with a flash time at least 5 minutes so you don't get any drips (photo771) It looks good, looks even better when finished (photo 772) Total cost for me so far was $26.12 Epoxy & $7.69 Gloss Black Paint, not bad.
This "how to" project is not over yet... I will continue in Part 3 Tony
