I messaged you on Facebook on march 17 as part of the thread in Gxor fb page but It looks like you have not read it yet.
I'm in for my gx460. I'll send you a message here as well.
I plastidipped the grill on my tacoma a few years ago. I did 6 really light coats and it held up perfectly for about 2 years. Additionally. I had an old beat up mailbox and got drunk and decided it needed to be black but all I had was plastidip. That was 8 years ago. And it still looks great...
