As for durability of “wet” paint, there are still hundreds, if not thousands, of factory-painted Pantera wheels that still have quite presentable finishes.
The factory used a zinc chromate primer prior to their top color coat. Obviously that industry-standard approach has demonstrated its worthiness.
hard to beat 50 years of durability.
not many of us will still be alive to evaluate the long-term durability of the non-factory methods.
