Anywhere to get a foam cannon for cleaning vehicles in BR?

You try Grainger?

Yea I know. I'd like to buy local as much as I can within reason.

Home Depot or Lowes

You've seen them at those stores?

MTM is the one you want. You will need to order it. Some brands call them a foam lance which may help your search.

Unless your car is absolutely filthy dirty, you really don't need one. I have one I got on amazon a while back, but I really only use it on detail days...though I think it was causing waterspot/soapspot issues on my paint so I rarely use it now.

Well, my main problem is water quality in Lake Charles + not drying quite quick enough. Using the foam as a pre-soak caused soap and water to dry near the bed-caps on the bed. Think I was using Griot's Garage car shampoo at the time.

I clayed, polished, and sealed last weekend, so good to go now. Used a "synthetic" clay for the first time and really liked it.

Just my opinion but I think the chemical guys lance is extremely over priced

Ive used the gilmour foam master and adams polishes car shampoo with good results.

some brass quick connects will make it easy to switch from the gun to water nozzle. I dont use the supplied trigger sprayer.
