Stuff works, I had it installed on the front of my '03 Vette, and almost 40K miles later, when I sold it, the front end looked new.
As for installation, if you were installing on a H3 door panel that is flat, it is easy. However, you really run into problems when installing on curved surfaces such as around the front of the rear fender flares.
As in the front of a Vette, those curves are hell to form the stuff around, and you need patience (something I lack), and experience.
I'm still looking for someplace in the Detroit area that installs this stuff, I want some for the front of the rear fender flares.
In this state, you don't need it for off-roading, you need it for driving the roads that are falling apart, and the road crews put cold patch (asphalt and rock) into the holes, and use your vehicle as the piece of equipment that levels the cold patch. I throw up more rocks on my way to work in the morning, then I do on 20 miles of Utah desert roads.
