Lives up to the hype
If you're on the fence — pull the trigger. The depth of finish after a single application surprised me, and water beading was textbook. Lives up to its reputation.

★★★★★
Solid pick for casual use
Works as advertised on light to moderate jobs. For more demanding work I'll still reach for something more aggressive, but this earns a place on the shelf.

★★★★★
Pro-level finish at home
Bought a bottle, used about a third of it, and got two full details out of it. Holds up well in real conditions. The instructions are clear and the product behaves predictably, which I appreciate as someone still learning.
