Boars hair brush vs. mitt to wash your vehicle?

I use the Montana 10" BH CarWash brush from AG exclusively with my SUV now. I use it on a pole for the roof, and in my hands to clean the rest. I also use it to clean all glass on my black BMW and the convertible top. First off, I just love how this thing feels in my hands. I just feels like a quality piece.



I did some testing with it. I did the "CD test", and found the brush will not scratch a CD if soaked properly (20 mins+). It hasn't scratched my vehicle in any noticeable way.

I do almost the same thing and use the same brush, except lately I like using (griot's) sheepskin wash mitt on the side panels, I find its a little faster. I haven't seen any marring, at least in direct sunlight.



I mix a little ONR into my car wash (also using griot's car wash), I think the added lubrication probably helps to avoid marring. Also, I use a smaller brush on rims.
 
Regulars here know that I'm a big proponent of the BHBs, but only when used properly.



It's tempting to use them *improperly* because they seem to hold a lot of wash solution and they lend themselves to covering large areas through the use of long, sweeping motions (which I consider absolutely :nono ).



Used properly, I find that BHBs are often too gentle to get a truly dirty panel clean (gotta avoid the temptation to press harder; you should not apply so much pressure as to bend the bristles over so the sides/shafts of the bristles contact the paint, you want to clean with the *tips* only). So I use the BHBs to get the "big stuff" off (the stuff that I consider primarily responsible for wash-induced marring) and then I switch to a mitt for more aggressive cleaning to get more tenacious contamination (e.g., "road film") off.



Of course I only use these two media with the constant application of foamgun output. One of the primary reasons why I like BHBs is that the foamgun's output (I'm deliberately avoiding calling it "foam" because that's not the consitency I want) will pass between the bristles and flush away dislodged contamination. In the absence of a foamgun I'd want to rinse the BHB very frequently; I sure wouldn't do a whole panel without rinsing, probably wouldn't even to *half* a panel. Again, it's tempting to use the BHB incorrectly (or at least what *I* consider "incorrectly). Once your wash media (whatever it is) has abrasive dirt stuck to it, there's a big risk of marring.
