Oh, you guys.....you get me thinking how I could maybe put up some huge "shower curtains" and start PWing :think:
It's so gentle it doesn't even hurt the dirt :chuckle: Hence SuperBee364's prewash with the PW. And the frequent need for some kind of more-mechanical follow-up wash.
I'll toss out my $0.02 on BHBs here.
The contact pressure with a BHB is *MUCH* less than that used with ONR. I barely contact the paint at all with a BHB, whereas with any type of MF/mitt/sponge you have to at least apply enough pressure to hold it against the panels, and that's a *lot* more than it takes to barely whisk the tips of the BHB's bristles across the finish.
I spray the BHB/point of contact with the paint with foamgun output. Noting that I have boosted water pressure that might factor in here, that foamgun output (no, it's not really foam IMO) not only provides soap and lubrication, but it also keeps the BHB rinsed clean.
You *can* see dirt on BHB bristles, but if you use it correctly there shouldn't be much of anything to see.
BHBs are *so* free-rinsing that you can pretty much flush away (potentially abrasive) dislodged dirt instantaneously with the foamgun, the moment it gets knocked free from the paint. Used without a foamgun, you just have to keep rinsing/redunking the BHB *very* frequently so it's always fully saturated with shampoo mix (hint: don't use a BHB without a foamgun
).
Moving the BHB (or any wash medium) in an interrupted, jiggling motion will help keep it rinsed out and will also minimize the severity of any marring that does occur. People move their media in long swaths and then wonder why they get foot-long scratches.
When I use ONR, I have to examine/deal with my wash media a lot more often than once-per-panel; it gets contaminated with dirt and I just don't trust the voodoo. Same, to an even greater degree, when using a mitt and conventional shampoo. If the dirt adheres to the wash medium, then marring becomes very likely.
But with the BHB/foamgun combo, no such worries. While I do still dunk the BHB in my rinse bucket as I feel necessary, by the end of the wash that rinse water is still almost entirely dirt-free because the dirt got flushed away rather than trapped in the BHB. IMO the only dirt in my rinse water comes from my follow up wash with the mitts, which don't rinse out nearly as well as a BHB.
SuperBee364 said:A long bristeled BHB "flicks" stuff off the paint like a broom, and if you keep the water flowing, it never gets a chance to stick to the bristles, especially if you keep dunking/rinsing it as often as you should. Properly used, a BHB is darn near as mar-free as not touching the paint...

efnfast said:Btw, I know you really like the BHBs, but how can you safely put them ahead of ONR+mf. Atleast with the ONR+mf you can go panel by panel and examine your cloth - if it has any dirt on it, stick it in the washing solution and rub it out then and there and the cloth is clean. With a brush you really can't see if dirt is adhered to it.......
