BigDeaner - Painting was all spray, I used dupli-color self-etching primer first, then the bed liner paint.
I did have to clean it all up first, since it came bare metal. Also I roughed it up a bit with sand paper, then I used mineral spirits and elbow grease, then sprayed it all off with brake cleaner.
Chirurgus - I mounted the control box under the hood on the drivers side behind the wheel well. I bought 2 gauge wire and ran it all. I will post a pic tomorrow of the wiring setup. I will caution that the wiring was not cheap! But I think it was worth it..
JRoweMDN - No issues with the bumper or install. The tubing is welded all the way around, no additional braces per say. Though I don't know if any of this style of bumpers has much for bracing on the tubes. Maybe they do though, I don't have any experience with any other bumpers unfortunately to say.
