If I interpret your initial question correctly I think you are asking where is detailing headed in the future, not as much tactically but more conceptually. In my opinion I would guess it comes down to paint technology progression and materials use, both inside and outside vehicles.
For example, Monica said she desires the return of "real paint" again. With the EPA stuff, that ain't gonna happen but where is it headed?
2 things I would like to see for us to remain progressive...1.) The IDA to grow in both membership and professional stature. A truly honest trade association that represents the interests of the detailing trade.
And 2.) a top shelf periodical published monthly and dedicated strictly to detailing. Basically an e-magazine that includes articles of interest for the DIY detailer at home working on their own vehicles all the way up to the high end pro businesses. In this online age, I would envision, like I said, an e-magazine but one that offers a wide range of information in ALL aspects of detailing. This product may even be an IDA publication but one with a transparent agenda towards bettering the profession and not bought by any specific corporate pursuits.
Now I realize many may think "e-mag? don't need it". This forum, a few others, numerous blogs, company website info etc. provide all the info we need...right? Maybe, but a centered publication from the highest authorities discussing tips, tricks, new current technologies, near future technologies, the "science" behind XYZ, etc. might feed those existing forums and discussion locations and help grow the industry. I can imagine someone starting a thread here titled "New IDA mag article" and propagating further discussion and perspectives here (and elsewhere) beyond what the author brought out.
I don't know. Just some thoughts but in my opinion I would like to see us on the cutting edge of new information gathering and sharing. We, here, are the rabid, involved and most passionate in the biz and we always want more info. I am not in any way sounding the death knell for places like AGO...au contraire. I think professional associations and an authoritative publication would bolster discussion here. I come to this forum daily for information and personal expression on a wide range of subjects. Just think of the banter back and forth resulting from the breakthrough article!!!
Now having said all of that, I am not so naive as to think the corporate agenda would remain seperated. That's ok however I would like the IDA and any subsequent publication to at least remain vehicles that provide me with information to spend my money wisely in an educated way.
