I used rock-it bed liner on my challenger. Looks like undercoating but will spray clean when washed. I know not everyone likes it, but this car will be driven daily. They like to use tar and chip on the roads here in summer also. So painting it wouldn't be a good option for me. I do like the factory look over paint. Paint looks pretty until its back on the ground and not seen much, so unless it's a show car, I see no point to it.
