I have seen a lot of nice high end seat covers in here that people have talked about. The nice ones are obviously made to stay on and look great. I just want something to be able to throw on once in a while, as needed. Any suggestions for an occasional use water/stain resistant cover that works decently? I was looking at various neoprene ones on Amazon but several reviewers said they had stained their seats. I think my head would explode if I bought seat covers to protect the seats and they actually ruined them! Thanks.
