I've only used the Concours (red). It's one of three I cycle through, the other two being Souveran and DodoJuice Supernatural. All look absolutely spectacular on my Imola red garage queen.
Easy on, easy off, huge shine, and believe it or not, its durability is huge compared to Souveran. Concours keeps it's shine so long, I think it's secretly a blend of carnauba and a sealant but of course, the ingredients suggest otherwise. It just seems that way because of its long lasting performance.
It's called 'Victoria' wax because it's actually based in Victoria, British Columbia, the capital city. I live about 20 miles north so there's a bit of a geographical bond but I've never met the owner, David W. I just like the product.
And I like the muted market strategy. Not a whole lot of hype, not a whole lot of marketing, the product stands well on it's own, and comes in 3 sizes of container. I'll often recommend a new user start with the 3 oz. sampler to get a feel for the product.
Actually, I'm running low on my current pot so I'll be picking up another this season.
