Hi Shaun--
You indicated that you are restoring a white wheel at the present time.
What color white are you using? Is it a Mecedes color-code white?
What type of paint are you using--enamel, acrylic, epoxy, color plus clear?
These questions about color have been posted in the past, and it seems that no one wants to divulge their secrets.
Thanks in advance for your advice and guidance.
Joe
