The media could not be loaded. This stuff is amazing! Goes on super thick, doesnt really run...washes off beautifully and leaves an amazing smell. The truck shimmers after like stars in the sky. You get an absolute bang for ur buck, and worth thr purchase. I used about 2oz of syrup for thr bottle, and didnt actually need to use the whole cannon container. This stuff is the biz. This is a foam cannons dream syrup. Spits out thicker then oatmeal, turned my mudbath truck into a white angel temporarily.

This Adam’s Mega Foam Car Wash Soap (Gallon) is an ultra-concentrated, high-performance shampoo designed specifically for users who prioritize maximum foam production and paint safety. It is considered one of the most effective "snow foams" for pre-wash routines

Adams Mega Foam works very well with or without my pressure washer. It foams so good that I barely use my pressure washer now

Great soap and solid foam. Smells like cherry hard candy

I’ve only tried two brands of foam — this one and Hybrid Solution Pure Wash by Turtle Wax. Pure Wash is notably less expensive. However, Mega Foam is more concentrated and I use between 1.5 and 2 oz in my 1000 ml cannon. Pure needs 4 oz. Mega Foam does create more suds but Pure is not far behind. Mega Foam has very good lubricity, but Pure has a bit more. Mega Foam leaves a glossy shine. Neither one cleans that well on its pre-soak but does clean with contact washing. Mega Foam is much better at preventing water spots in sunlight and hot weather, and that’s what is the determining factor for me. Buying it in quantity does knock down the cost per oz and it’s more concentrated, so it won out as my go-to soap.

Great car wash and foams wonderful with a pressure washer or garden hose foam gun. Its not quite as aggressive as meguires gold class on bugs and bird droppings, but its perfect for the guys who wash their car every two weeks or sooner. I like that its ph balanced and essentially wont wear down any coatings you applied as fast as meguires gold class would.

Great smell awesome foam out of my new Addams foam cannon super thick foam

This soap works well with my auto pressure washer. It leaves thick suds that will stay on car and soak for several minutes. I use about 3 oz in my foam cannon and use that for one car, although I typically have about 25% left over. I rinse, soap and let linger, wipe with microfiber mitt if particularly dirty and then rinse. I would say touchless wash is a myth, but I still consider this entire process much better than the old two bucket method.
