At Carlisle last year when some dudes and dudesses (thanks Rich) were squirt detailing in the Marriott parking lot I asked someone (I forget who) what brand he was using. He replied "Ah, they're all about the same"...OK, so I bought a Turtlewax product.
Couple of weekends ago I was hob-knobbing with some club guys at a show featuring some very cool Rods and Customs, and the subject of detailing liquid came up. It turns out they all use, and swear by Surf City Garage 'Speed Demon' Wax Detailer www.surfcitygarage.com... So I tried it.
I have no experience with McQuire's, Mother's, etc., My black VS isn't dull, but in sunlight it almost has an underlying brownish hue. This stuff snapped it back to a glossy reflective black. I couldn't be more pleased.
Tim Miller, founder of Surf City, claims it's the only detail spray with "pure #1Brazilian Carnauba"...and if it isn't the best I've ever tried he'll buy it back...Well, I'm skeptical of hyperbola marketing superlatives, but this stuff certainly shames the Turtlewax product!
