I use about 21 different "brands" of products and most of those haven't changed over the past 5-7 years. I use, and then reorder, what works best for me in my business.

I've been doing this for over 20 years and have reached a point of simply reordering the least expensive product that works the best for me. Lowest cost product along with exceeding customer expectations is how I do it.

I will fall prey to trying a product that affects or introduces a process change. E.g. iron removers. That product introduced a refinement in the decon process. I then tried all of them at the time and have settled on my favorite. Another example is a "better" abrasive such as 3D AAT. Tried it and went back to my Menzerna, Sonax and Griots products. I WILL be giving 3D another shot now that Mike is there. My experience may certainly have been my process or technique.

As Mike says...find what you like and use it often.
