Hello!
Im from the Uk, maybe you can contact CARWASHWAX.CO.UK if you want chemical guys stuff? Very good service, and most of the Smartwax gear is very similar to the CG but more expensive. In the UK, but mainly in the USA SmartWax is sort of an OTC brand, you can find it in car dealer showrooms. In the Uk you can but it in a few shops.
I have used the Smartwax line here is what i think:
Shampoo, really nice, cool colour smells good. It leaves the car looking awesome and has pretty decent cleaning power. I rinses freely enough and does have quite good economy. ITs very similar to Extreme Wash n Wax but a different colour.
The blue QD is just like CG's blue QD with Nuba. fairly lubie, i would not use it as a clay lube though, leaves a really nice finish.
Smartwax is a cleaner wax, it cleans and fills. Durability is about 5 weeks, best topped with the Sealant. The sealant is a mix of Polymers and Nuba, i would say it was very similar to CG's Top Coat with Nuba and Poorboys EX sealant with nuba.
The Carpet cleaner is top stuff! The trim Gel is very wet looking, dont use it inside your car its far to fake for my likings, on tyres it looks good.
All in all, nice products that you can buy cheaper from Chemical Guys own brand, the only thing i buy is the soap and QD when it comes up cheap on Ebay. A while ago in the UK you could get a back of 4x2oz samples, i dont know if your national distributer offers these.
