Finish Kare 425 get the job done.
I have been using this product for a couple of weeks and the results have been excellent.  While most sprays will give a good result with painted metal surfaces, a plastic tonneau cover is another issue.  It builds up a lot of static quickly and it makes getting rid of dust very difficult.  Finish Kare 425 has done a much better job than other sprays have.  To get the best results use a good microfiber towel and a spray bottle that produces a very fine mist.  I didn't like the 31oz spray bottle that Finish Kare supplies so I used one of my own.<br /><br />I haven't given this product 5 stars because I haven't been using it that long but if my experience with the product continues to be good, I'll update the review and upgrade the rating.
