Hey everyone,

I thought I would give you guys a little sample of Kevin's paper. One of the most important topics covered is pad priming. Although it may seem simple, I wanted to clear up some confusion.


When I refer to pad priming, I am referring to the liquid that will be used in polishing - not a spray detailer.

M105, M205, M86, D151, SwirlX, ScratchX 2.0, and Ultimate Compound use abrasives that are uniform and non-diminishing. That means that they are very different than most products that use abrasives that break down. These products that use non-diminishing abrasives rely heavily on the lubricant. If there is too much lubricant, then the cut will be reduced because the abrasive is floating in lubricant. If there is too little lubricant, then the product will "flash" very quickly and you will need to reapply product.

The best way to utilize the products listed above (non-diminishing) is to prime the pad. To do so, take the product and pour some on the pad. Then, rub it in. You are not trying to spread butter on toast. Aggressively rub the product into the pad until the entire surface is covered.


To show the method, I chose M205 and a W9207 finishing pad.

Below is an example of a poorly primed pad. As you can see, the product has completely filled in each of the pores. This will waste product and reduce the cut.

Here is what a properly primed pad should look like. The pores are not filled with product, but there is still product available in the pores.

To give you a better idea of what the pores look like, I took a macro shot of the above pad properly primed with M205.

Hope that helps!
 
I have been hearing about this Kevin Brown method and want to know more about it!

Is there a original post to the theory of this method???

thanks,

I think there is suppose to be releasing it in the next week or two :cheers:
 
How were you able to get it all in evenly like that? I'm having a hard time imagining how one can get a pad so evenly spread with product without it being used on a panel or two already.:confused:
 
Very cool, thanks for the info Porsche dude.

No, I did not use the pad and then take a picture. I just pressed my finger into the pad and scraped the excess product off. This left the pad perfectly primed.

If you look closely, you can see some stripes in the pad, too.

Thanks PorscheGuy! Makes sense that non-diminishing polishes would need to be primed well to get nice even results.
I use Menz IP and FPII, and I prime thoroughly with them. Waste of product? I'm happy with the results..

Out of curiosity, did you just work in the polish on the improper pad a little more to get it right? Or are they different pads?
 
So what's the next step?

After the pad is primed, you can go ahead and start using the pad as normal. I usually apply four small dots or a thin circle, but it really depends on your work area.

The idea of pad priming is to speed up the way the polish spreads on the pad and to make sure there is polish available in every pore of the pad. Without priming the pad, it might take a few passes before the pad surface has product in every pore. Even then, the product might not be evenly distributed.

I would not prime a pad with IP or FPII. Diminishing abrasives break down randomly. So, you might end up with some inconsistent polishing. It is very important to keep the pad clean when using a product that utilizes diminishing abrasives.

That's good to know. I still have loads of IP & FP II
 
Is 3M Perfect-It II considered a non diminishing abrasive compound?
