B_to_C can tell you all about 4x4 Armor. The are basically out of business as near as we can tell.
B_to_C ordered a front bumper from them in late December, and it still isn't here yet. The worse thing is that they already have his money.
He's tried contacting them. The phone number he has doesn't work, and the website is gone as you know. Last news was that the owner was in the hospital with a stroke, and then within the last few weeks he got an e-mail with some vague information about a change of ownership. Still didn't provide any contact information or respond to his reply to that e-mail.
