Best shampoo to use with Foam Gun
 

I recently started using a Gilmour Foamaster II gun for washing my car. I've tried it with chemical guys Mr. Pink and Meguiar's gold class. With Mr. Pink it leaves some type of residue on my Obsidian black IS 350 that makes finger prints and smudges very visible, especially in sunlight. The Gold class did a little better, but I hope that there are better products out there that work well with the foam gun.

I'm quite turned off with chemical guys at the moment. Most of the products I've used from them (sealant, shampoo, wax, microfiber cleaner etc.) seem to be overpriced, overrated, and overhyped.

Does anyone have other brands they would recommend for an inexpensive but effective shampoo that works well with the gilmour foam gun?

Chemical Guys is great at 2 things.... marketing to the 'general public' and selling tons of products. I would agree that the vast majority of their products are overrated and overhyped. They have a million products that work fine, but none of the ones I have tried are outstanding. Stick to tried and true brands like Meguiar's. Their Professional line of products is outstanding.

2 of my favorite maintenance shampoos are...

Meguiar's Hyper Wash
Optimum Car Wash

I am relieved to hear that a pro like you shares my opinion of CG.

Thanks for your recommendations. However, from reading the product details it doesn't look like the recommended application is using a foam gun. Or is that not correct?

Most pros share that opinion of CG ;) As I mentioned, they target the consumer market heavily.

That is not correct. Both options I suggested can be used traditionally (in a bucket) or in a foaming device. A foaming device is never required for any shampoo.

I share the general skepticism of CG's products but their Honeydew Snow Foam is legit. Give it a try, you won't be disappointed.

I have the same foam gun, and I use Gold Class. It studs fairly well, but I still do a two bucket wash afterwards.

The foam gun is really to break some dirt down, and rinse away before I wash.

I was tempted to try Meg's Wash/Wax, but its pretty pricey for the amount you're getting. Gold Class, imo, is relativity cheap and last awhile.

*Also, CG stuff is kinda overprice, imo, and I fall into the "general market" category. Can't go wrong with Meg's products, everything I use for my car is from them.
