First of all, know that I love Adam's stuff. Living in Denver, it's great to be able to pop up to the HQ and pick up what I need, when I need it (be it Louisville or Thornton).
One thing that might be helpful is a product line flowchart/compatibility chart. I acknowledge there may be a downside to saying "don't use this with that...." and I also realize that if you watch all the Adam's vids this information can be collected, but here's an example:
H20 Guard and Gloss: This is a great product--one of the best out there. But supposedly you don't use this with ceramic coated cars. So, there might be a "wax path" chart. Then perhaps a "sealant path" chart. Finally, a "ceramic path" chart---with attending why one would use any particular approach.
As I've said, I think the content is already out there--but in multiple places. For instance, in the original ceramic vids, Adam says one would use this when the vehicle is kept outside, driven in the winter/chemicals, etc. Whereas someone on the "wax path" (or whatever you want to call it) is waxing a show car or a car that's kept inside and driven infrequently. Like I said, these aren't necessarily secrets, but for a casual user (or even a sorta-casual, sorta-weekend detailer user) it's nice to have ready reference. Heck, maybe it's out there and I've missed it.
