MFDB I tend to feel the same way. You can't hardly go wrong if you trust Honda's judgment.
I first read about Micro Blue in an article about Robby Gordon's new trophy truck. When it was being built in '06 I think? Robby said he was excited about some new technology he was using by REM Chemicals. I heard about them again when Darrel Waltrip said on Speed Vision last year that Toyota has ALL moving parts of the car treated in a similar manner, and not just the engine / transmission like his competitors. This he felt was going to give his team the winning edge.
I know nothing of this first hand. And I don't pretend to understand all of it either. But this is what Micro Blue has to say about it. And whereas it's content goes against our collective opinions, it's informative non the less. And sometimes it takes an idea much different than those two decades past to drag the evolution of our sport one inch forward.
"Lubricant Heat – Where it comes from
In engines and transmission assemblies, the moving parts rarely touch each other. The crankshaft in your engine does not actually ride “on” the main bearings, there is an oil film that separates the two surfaces. So to oversimplify things a bit here, we use lubricants to (hopefully) prevent parts from touching and also to reduce sliding and rolling friction. So if things don’t touch, where does the heat come from? To answer that, let’s look at a typical 4 speed transmission. As the gears rotate, the gear oil is pushed out from between the gear surfaces, this we all know. However, as the oil is pushed out, a certain amount of “turbulence” is created as the oil has to navigate through the “peaks & valleys” of the machined surfaces. This turbulence causes the oil to work against itself and that friction heats up the gear oil.
Lubricant Turbulence – The relationship between surface “profile” and heat
When it comes to machined parts, we all agree that “smoother" is better. That’s right, but remember that there are still “peaks & valleys” with turned, ground and even lapped surfaces and all create some degree of turbulence and increased friction. After processing, the surface is now, from a functional standpoint, "optically flat". The net result is dramatic reductions in heat, wear and friction properties. So how do we do that without changing the size of the parts?
The Isotropic Surface “Profile” – What it is
As we said, conventional machining and polishing processes result in a surface profile that produces grooves (peaks & valleys) on the surface tend to all point in one uniform direction. All too often, they run perpendicular to the direction of the oil movement, creating even more heat! Well, the term “isotropic” is used to describe a surface that lacks any “directionality”. There is uniform direction in which the grooves point to. Compare an old 33 rpm record to a hand mirror. The mirror has no “directionality”.
ISF® (Isotropic Surface Finishing) – What it is and why it’s better
Now that we have a good understanding about just how the “peaks and valleys” create heat, it is easy to understand how an “isotropic” surface can greatly reduce heat build up. There is a process developed by REM Chemicals, Inc. of Southington CT that does just that. The parts are placed in a standard vibratory bowl that is filled with a non-abrasive, polished ceramic media. A chemical compound is introduced, that forms a 1 micron film that follows the "peaks and valleys". On contact with the media, the film is removed from the "peak", in effect, "flattening" the surface. What makes their process unique is that the film re-forms on the "peak" only, with no other surface interaction as opposed to electro polishing, for example. Due to the very gentle action, we can now improve almost every moving surface in a race car, snowmobile or go-kart. Very nice! For more information, go to:

*A note regarding "size change": It is important to understand that the ISF process is very "un-evasive" in terms of dimensional changes, unlike electro polishing for example. Obviously, we cannot refine a ground surface without some degree of size change, but from a practical standpoint, the changes are insignificant. For example, if you were to measure a 1" shaft before and after, you will not pick up a tenth with a micrometer. We recently measured an 4" Xtrac spur gear after processing and saw a reduction of 60 millionths over pins.
MicroBlue® & ISF® - A truly amazing combination
When we add a coating that changes and improves the way a lubricant works, things get very, very interesting. During the early development of MicroBlue, we were able to do some testing on a high-speed milling machine that used pressurized, “hydrodynamic” (oil film) bearings instead of ball or roller types (the same bearing type as crank & rod bearings). We were measuring the current draw on the DC motor as well as the temperature rise of the oil. After coating, the reduction in friction and heat was clearly evident. However when we ISF superfinished and re-coated the rotating spindle, the improvement just shocked us (see chart). We knew right then and there this was an unbeatable combination. How well does this combination work? Well, recently a gentleman called that runs in the Hooter’s series. “We’ve been running Royal Purple in our quick-change rear-end for years. This is the first time it has come back out purple! I’m tell’in you, we saw a 100 deg drop in oil temperature, honest” (true story)."
