Amazing Products!
I had my SUV professionally ceramic coated with Gtechniq products and I can't say enough great things about it! All their products are amazing. It's all I use now and couldn't be happier. Love Gtechniq!

Great products, time tested results , consistently. Will always recommend gtechnia
Their line of car wash items are great. I use it on both my cars. Products are good quality. Foams well and removes media effectively. Their shipping and packaging is on point. 25 G80 M3 MT 22 Etron sportback 95% of of my car wash supplies come from Gtecniq. Definitely recommend.

Amazon shipped is trash
Product is great, Amazon packaging is trash. This is the replacement for the first bottle that was crushed and leaking in the same spots. At this point I'll keep it and move it to another bottle, but Id order directly from the company site and skip Amazon.

First ever shampoo for my first ever pressure washer
I have been doing Rinseless wash, so never had any chance of visiting foam town! I always though, it's kinda gimmicky. But, after using this for the first time, it looks so clean! Specially, I like the fact that it clings to the surface. Let it dwell for 3/4 minutes before washing it off, otherwise it won't be effective much. Gtechniq is always my first choice when I shop around as my car has Gtechniq crystal serum ultra. This one works very good with the ceramic coating. Smells good, also the price is reasonable. It doesn't add any protection, and that's also a positive thing.

Ho preso questo prodotto per la mia auto... L'ho utilizzato con una Foam Hose (pistola schiuma classica no idropulitrice) Il prodotto è ottimo ma credo che dia il massimo con l'idropulitrice Non funziona con un erogatore spray manuale o/e pressione. Ottimo prodotto se si hanno gli strumenti corretti.

Benutze dieses Shampoo um mein Auto zu waschen. Habe dann noch soeine Handschaumsprüh Maschiene und das funktioniert gut. Gute Gleitfähigkeit und angenehmer Geruch.

Produit qui s'applique bien avec mon nettoyeur haute pression. Je suis content du résultat. Le flacon était très bien emballé.

First time using this but have to say it’s really good stuff. Seen a few comments about beading and water not running off on other Gtechniq products, seriously, do people think the rain will dodge their cars after applying? It’s good but not that good!!
