I think you guys that consider yourselves experts have to realize that what works for you, doesn't make it gospel. Every car, every paint is different even coming off the same assembly line. Then throw weather conditions into the mix (what works in Florida or California doesn't mean a whole lot up here in the north), and you have the reality that things said on here that perhaps worked for you...is not necessarily going to work for me, and I find that true more times than not.
I have boxes of products that I bought because of recommendations I've read, only to find that on my car, or in my location under the conditions I drive...they are just not as great as I was led to believe. Chemicals react differently to weather and paint type...so frankly, if you guys really want to express expert opinions on products or techniques...then do what "Corey" does when he reviews products.....put in your post all the conditions that are relevant to the situation...temperature, humidity, type of paint, technique, etc. Were manufacturer's recommendations followed, or are you doing your own experiment?
Many "experts" don't go into detail like this, so I take EVERYTHING with a grain of salt no matter how long you've been detailing cars, and I especially see red flags when I know that something in sunny Florida may not last very long in NY state (case in point...sealants).
The new Optimum Opti-Coat 2 is all the rage on many car forums these days. Let me tell you...no matter how "easy to apply" and how "great" this product is on paper...I always ask myself BEFORE I'm going to apply something PERMANENT to my paint....what conditions do I have to duplicate to get the result I want?
I will always do my own test regardless of who is writing the article because variables cannot be duplicated across the Internet, and because we are talking primarily about chemicals...if you know anything about chemistry...chemicals are not going to react the same when the variables change.
Finally, I don't mind guys posting that are not experts because if something is said that is way off base, it will be pointed out, and people will be educated in the process, and a dialogue/debate will ensue. Yes, its always great to have expert opinions, but they are just that...opinions, and we all must remember that because no two situations are alike, and how boring a world it would be if just the experts posted threads or answered them.
