Sleek finish, easy to use
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 Koch Chemie formula goes a long way per panel — a little really is enough.

★★★★★
Decent for the money
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.

A solid addition to the kit
I picked this up after reading the review here and the results were exactly as described. Koch Chemie 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.
