One thing that may help is for me to tell you guys what we were trying to do when we brought Opti Eraser into development. I personally never clay unless I plan to polish simply because I know I will be adding some fine scratches. But, all my waxes and sealants naturally bond better, look better, and last longer if the paint is decontaminated. The chemical decon alternative is good, but expensive and they always work better if you remove the above surface (bulk) of the bonded contaminant first. S the challenge was to create a product that would remove above surface contaminant while inducing little-no marring or it's own. Opti Eraser does this very well when used properly.
It's not a direct exchange for clay, so there is some adjustment to the technique necessary. Proper lube and back/forth movement are the same, but because of the foam interface and perfectly flat surface you'll need a couple of adjustments.
First, there's very little need for downward pressure so you should grip the Opti Eraser on the sides with your thumb and fingertips without pressing down with your palm. You can also squeeze it slightly to give the working surface a slight convex shape that will lessen drag on long flat panels.
Second, the foam interface and the nature of the polymer face (while allowing mar free decontamination) also reduces the tactile sensitivity when compared to actual clay. Simply wear some nitrile gloves so you can check you progress as you go. It is very similar to the feedback from the baggy test and is more accurate than the feedback from clay.
I still use clay on the brutal stuff, but Opti Eraser is my every day pre wax prep tool. I can No Rinse a panel, Opti Erase it, and dry it in a fraction of the time of claying and there's no residue like I get from clay sometimes...which means I can go straight to wax or sealing with no further cleaning or polishing. My customers get a better looking finish with very little effort on my part. It may have a place in your process and it may not...but, if you need mar free decon you have nothing to loose with the satisfaction guarantee.
