I have a Colgan -(Fits great) but the look is not as good as without it(my opinion). HOwever, I use it on long road trips to avoid stone chips and a large amount of bug guts. I also use it in the winter when I need to take the car anywhere (it's parked most of the winter). Sometimes you get a sunny day in December and want to take it out but there are a million little chips on the road. So to answer your question, they work well for what they are intended to do. You just have to take care of your paint underneath. Hope this helps. Kevin
