Carlack Glass Finish

Carlack Glass Finish

Overall Auto Express rating

4.0

Carlack's Glass Finish is our pick of the conventional repellents and secures a podium on the maker’s debut in our tests. You apply it to a clean screen with a paper towel before leaving it to dry. Next, you moisten it and buff the windscreen clear. Yet it’swell worth going through this complicated process, as the product certainly works. Glass Finish couldn’t quite match our top two choices in this test, but it was clearly ahead of its big-pack rivals and showed little sign of slowing.
