Wow !
I myself have noticed how much negative comments are floating around about Wilson speakers.
Hearing about defective paint is not surprising, transporting will almost guarantee some kind of issue , not to mention the difficulty in preparing and preventing faults that tend to show up months later.
2 months turn around for a painted custom finish would not be considered unusual and is about right as the paint has to cure to make sure there will be no shrinkage that would lead to further cracking before transporting . Also i can see Wilson holding the speaker a bit longer to make sure all was good , before shipping knowing any faults here would be very irritating due to it being a re-do .
A custom color would add time , as WA would not setup just to paint one Pr of speaker, you would naturally do the larger run first .
I would hope the O/P would chime in to let us all know how this ended .
