Thanks for the step by step, I did in two of my wheels and waiting for the weather to clear up to fix them.
I think others asked where did you get the paint color, I am not familar with the brand you used and silver is one of those tricky colors to match correctly. I think adding the brand and part number of the paint will help everyone.
A little added advice, generally speaking aluminum usually required a special primer, you can not use primer made for steel. Aluminum primers are also hard to find. This may not be much of an issue if you do not sand off too much factory primer and paint. The less you remove the better off.
