So seeing how foam and suds really dont matter in washing as I am told, IE QEW, what is the purpose of this tool?
Yep, that`s one of the good ones made by Gilmour.Originally posted by Blackmirror

You`ll have to read through it, and I think there are links to older threads in there also, but it should give you a pretty good idea on the theory behind them.

That thread was pretty good. I still have questions about it. How do I use the metering screw on top of the mixing head? I guess the more I tighten it the less water/soap come out? And what does the locking screw at the end of the stem do? I tightened it and I could still move the stem.

I have the same gun made by Gilmour (the Simple Green version), and the only adjustment that seems to do anything is moving the brass rod to a different hole to change the foam ratio. I just got mine for Christmas and have only played with it a couple of times so far, but they do come in handy.Originally posted by Blackmirror

Is this the Gilmour you guys are talking about?

That one is similar to the one I have (Butchers). You just want to move the brass rod back and forth. That changes the soap mix. Rotating the rod so the holes are not on top will give you straight water with out soap.
No, that isn`t it. That one looks like you`d use it for garden/lawn applications. There are various links in other foam gun threads for the "correct" Gilmour gun, but I can`t really find them right now. Gilmour makes them for at least 3 different vendors with the only difference being the colors and size of the bottle. Here is a link to the Simple Green version I have, but I think you can find them cheaper. Maybe Blackmirror or OI812 will post the link where they bought their guns.Originally posted by Spilchy

I do like the Simple Green version because it has a 1/2 gallon bottle, and I found that I use more foam than I initially thought I would.
John
I don`t care as much about how much foam is produced as I do the constant stream of flowing soap solution the foam gun affords. To me, its this constant stream of soap that makes a huge difference in eliminating wash induced marring.
I think some past threads hjere as well as one on Detail City show the right foam gun. Spilchy, I thought you already ordered one? If not, maybe the store in NJ might be your best bet: still decent pricing and probably next day delivery.
Treat it like it`s the only one in the world.

This is my understanding of the process-
A car wash concentrate contains a surfactant; this is defined as a material that can greatly reduce the surface tension of water when used in very low concentrations. The hydrophobic hydrocarbon molecule encapsulates the soils, which in turn are rinsed away.
By using it in foam gun the liquid is delivered to the surface (via the foam) and the soils are encapsulated by the surfactant and then rinsed away. The delivery of car wash within the foam avoids the need to agitate and lessens surface marring.
QEW also uses a surfactant, but it is contained in a very low foaming liquid, and it is correct that the amount of foam (suds) produced by a cleaning product has very little effect on its cleaning abilities.

What gets overlooked too often is that one must be a student before becoming a teacher.
I did a search on Ebay to see if I could find one cheaper.
I think I found a good one for WAY cheap.

It keeps the stem from falling out. See how the knurled locking screw is larger in diameter than the adjuster rod/stem that it screws into? The purpose of the screw is to keep the rod from falling out of the mixing valve. The pin keeps the one end from sliding out and the screw keeps the other end secure.

Yep, that`s the theory, which seems to be borne out in practice. It changes the mechanics of the wash from "scrub the dirt off and let it stick to the mitt" to "dislodge and flush the dirt off the panel". My mitts and rinse water don`t get *nearly* as dirty with the foamgun as they do with more conventional techniques.
With really nasty dirt (e.g., winter grime) I spray the foamgun through the bristles of a BHB. The risk of marring from the brush seems to be overwhelmingly balanced by the advantages of not rubbing the gritty dirt into the paint. It`s pretty remarkable what you can wash off the paint *without marring* when you use a foamgun.
