My car was a Phoenix car before I got it. Much cracking and fading everywhere. My advice is stay away from cars that have lived in high heat. I have learned the hard way both on cosmetic and mechanical issues. So, my louvers WERE so faded out I thought I'd never recover them. I tried "Black Magic" but it wore off so quickly it just wasn't worth it. I finally got my bottle of Vinylex (the same folks that make Lexol). Well, this stuff is fantastic. Two months ago I used it on my louvers. Against the reco of the instructions I was generous in application because the louvers were so badly faded and dried out. I have not touched them since and they still retain the blackness. Further, I used the stuff on the black vertical "vents" just behind the doors. Those used to go back to grey within just days. Those too still are black. So then I used the stuff on my interior. I haven't touched up since that application two months ago. Same on my exterior trim lines. The one area where it didn't last as well was the tires. They are still better than when I've used Armor All or other things. For tires, just because of the extreme wear/heat, anything will require repeated application. I can live with that. I rarely make product recommendations because I rarely find somthing that I like enough to put my name behind recommending it. Well this stuff is incredible. As you all know, Armor All just makes things worse. This Vinylex WORKS! Since I am not willing to promote any individual retailer, you can just do a search on the name and you'll be able to find online sellers for it. I've never seen it in a store here in Seattle. As a related aside. Lexol (the stuff for Leather by the same company) has so far been only marginally satisfactory. Better than Armor All for sure on the leather, but not the perfect solution they make it out to be. Many web references I've seen recommend it. However, I'm anxious to try out a product called Leatherique. I understand from many web posts that Rolls Royce / Bentley owners clubs along with a few other similar caliber clubs swear by this stuff. Has anyone used this stuff? What are your thoughts on it? Versus Lexol? thanks, shiraz
