Well, in theory it should work fine. I am still a bit scared of the BHB.
Look for Accumulator's posts on the BHB. He seems to really have the BHB technique down to where he doesn't get any marring. He'd be the one to ask about the BHB's.
I think that as long as you keep it free of any debris with a second rinse bucket and don't scrub away at the dirt, you should be fine.
For some reason, I still prefer cotton chenille pads for my Opti No Rinse or QEWing. They just seem hold enough solution, glide over the paint and rinse easily in the second bucket.
