The ABC system should take care of most of what you are concerned about. It is pretty good stuff. If you have access to it then it is a lot safer than the old Dawn or vinegar route that a lot of people use. You are still going to want to clay though. The ABC system will help out quite a bit but it isn't really a substitute for a good clay job. The ABC will help with the IFO (industrial fallout) but the clay will still help in removing other contaminants. That is just my experience with it. I only did it on my rear bumper where the IFO was really visible and the finish was much smoother after I clayed it after the ABC treatment. That was just my experience though. I'm sure you could email autoint about it and they could tell you for sure if the clay is really neccessary.
