| The legitimate "hype" is that you can use the foamgun to avoid wash induced marring and the resultant need to abrasively polish.
As noted it *does not* make the wash quicker/easier, it provides added protection against marring. At least the way *I* use it. I've never foamed an entire vehicle. While some people use it that way, and/or to make the wash go faster, that's not *IMO* the point in using one.
If you want to use it to make the wash go faster, use it in conjunction with a BHB, with the "jiggle" method I've previously described. You're working inch-by-inch this way and won't get suds all over. You can wash a very dirty vehicle, without marring the paint, in a fairly short period of time using this approach (but it's physically and mentally demanding).
I have boosted water pressure in my shop and I do sections of panels when I wash. By directing the foam at the point of contact between the wash media and the panel I don't get foam any place except where I want it. FWIW, I have other vehicles parked *very* close to the wash bay these days and I don't get any water/suds/etc. on them unless I'm careless when I rinse.
I too used it a few times, thought it was a toy, and put it away. But then I started really *thinking* about it and developed a conceptual understanding of how it could contribute to the wash process. Then, I must've used it a few dozen times before I attained a modicum of expertise with it..For that matter, I've used it for a long time and it was only this past winter that I really figured out how to use it with a BHB. |
