Hi Kevin,
Yes, those rims don't look like they will polish out. You can sort of make out how deep they sat in the dirt all those years.
Love the documentation on your restoration, it's been very helpful seeing what you did, thank you.
Looks like ebay has a few rims in Thailand that cost less than the shipping.
If anyone has recommendations on buying rims here in the states at the same or slightly higher price, please post away with your recommendations. Will also be looking for some nice whitewalls.
