Sleek finish, easy to use
I picked this up after reading the review here and the results were exactly as described. Milwaukee clearly knows what they're doing — application was straightforward, the finish is even, and there were no streaks left behind. Will be keeping this in the rotation.

Saved me a trip to the detailer
Used this on my daily driver last weekend and the difference is immediately obvious. The hood looks like glass again. Easy to apply by hand, didn't take long, and clean-up was simple. Recommended.

A solid addition to the kit
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.

Saved me a trip to the detailer
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.
