★★★★
Will buy again
Honestly impressed. I've tried a few competing products in this category and this one out-performs them on application speed and final gloss. The DeWalt formula goes a long way per panel — a little really is enough.

★★★★
Works well, takes practice
Decent results for the price point. Easier to apply than some pro-grade alternatives I've used. Wouldn't say it's the best in class, but it's a reliable everyday choice.

★★★★
Sleek finish, easy to use
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.
