I am thinking of getting a foam gun/cannon. I am currious to find out what people think between the air foam guns and the water driven ones. The air ones are twice the price but seem to lay out more foam than the water driven ones.

Any suggestions and experiences? It is the last thing I need to add to my arsenol of detailing supplies for now.

 

I've got an Autobrite one, buy one from UK and save about $50. Same as the Autogeek ones I believe.

 

And yes, you do need one!

 

You want the foam to absorb into the dirt/particles you're trying to prewash away. I imagine that air foam guns won't be as effective as water ones due to less water. Just get the Autobrite one or the Autogeek version. They are one and the same pretty much as long as it is the Cannon you're getting, not the Gilmore Foam Gun
