Thank you all for your thoughts...... I called the good folks at Micatech today.
I am not the first to call them with this question. And they actually HAVE re-painted a client's boxes.... but it was a ton of work. At this point I think it's one of those things that requires me to "leave well enough alone".
Testament to this product: 90K confirmed miles of use and they are absolutely SOLID and water-tight (despite the faded exterior).
Wish more things wore this well.
My plan is to get creative with them. I'm thinking a unique camo design.... hell, it's not like I will ruin the "look".
