Like most everyone else I have been looking for that miracle cure. I used to have a '94 Bounder and we did 4 costs of Zep on that and was amazed. We now have a 2001 Bounder. The base color is fine but the vinyl graphics have seen better days. We have some Zep left over so I figured I had nothing to lose for trying it. It wasn't gonna look any worse. I did a test spot and as you can see by the photo it does make an improvement. I only did a section of the brown and the lower green. It doesn't restore it to day one but it sure looks better. Tomorrow I will do them all !
If you have friends who make you laugh, spend lots of time with them.
