CarPro is the broadest line we carry, and the one a working detailer is most likely to have three of on the bench already. CQuartz is the coating family, Reset the maintenance shampoo, Reload the SiO₂ spray sealant that arguably created the category, and TRIX the tar-and-iron combination that saves a step on a neglected car.
The reason CarPro shows up in so many shops is dilution economy. Reset at 1:500 and Iron X at ready-to-use are doing very different jobs, and the line is honest about which is which. Working times are published, not implied.
CarPro’s weakness is the same as its strength: the range is large enough that two products overlap and the names do not tell you which to reach for. Dquartz, CQuartz UK 3.0 and CQuartz DLux are three coatings for three substrates, and the packaging does not make that obvious. That is what the specification block on each of our product pages is for.
Canadian supply is claimed by Auto Obsessed. Pricing moves a little between retailers, which is unusual in this segment.
