I learned from the Best in California specific to these cars, Lynn Park
Once a year soak each side in WD 40 (the cleaner)
After the soaking rag dry then prepare for the final coat of gun
oil
Gun
oil does not sling and will penetrate and protect for at least one year (protection)
Wipe off excess and you’re ready to go
Are usually do this over a trash can to catch grime and drips
Works well on this coast of the US where the environment eats everything.
My wheels are naked except for the
oil.... 6 years now
PS I do not polish the lips. If you do just use metal polish and oil to protect.
