I ordered the wrong stuff from meguiers, getting their regular PlastX cleaner and the polisher instead of the #17. What I got does nothing for the brown, hazy convertable window I have. Is the #17 really that much better? Is it worth ordering? Ive tried about 3 different products and have had almost no results yet.
