June 15, 2017: Adding some info at the top of my review. For owners of aluminum body vehicles, like me (2015 F150), see my picture below of the 24 gauge paintlock (pre-primed steel sheet) that I Gorilla taped with permanent double-sided tape to the roof of my truck. I get the same signal boost that I got when the antenna was on my 2011 truck (steel body). I've been on the interstate at 80 miles per hour with no problem. I mounted it a little more toward the back where the roof is very flat and out of the wind stream. The paint isn't a great match, but you can't see the metal unless you get in the back of the truck (which is where the picture was taken from). I suppose semi-truck drivers will get a good look at it. I'll report back if any problems arise...
