Stain, Stain, Go Away

I purchased a ’06 Mustang GT premium convertible with 31,500 miles on it in April 2011. It is Redfire Metallic with a Parchment (tan) vinyl top and Parchment interior. When I bought it, I noticed some dark stains on the convertible top just over the side windows and near the outer corners of the rear window on both sides. The former owner said they could easily be removed using a convertible top cleaner. I have tried various top cleaners, including RaggTopp, and have not been able to remove them. The rest of the top cleaned up great but that just makes the stains stand out even more! This top is in otherwise very good condition with no leaks. Do you have any ideas on how to get rid of these stains other than replacing the entire top?

We’ve heard good things about the RaggTopp product so we’re a bit surprised it didn’t remove the stains. Of course, without seeing them first hand, it’s hard to say what they are from. We’d have to guess it is plastic staining from the trim around the top. You might want to try Meguiar’s M40 Mirror Glaze Vinyl & Rubber Cleaner. It’s part of Meguiar’s professional line, so you’ll most likely have to visit a paint supply store to find it. If the staining is bad enough (or if it is actually top wear and not stains), you might have to resort to having the top dyed. Trim shops can handle that or, if you’re up for it, you can find top dye through online retailers.

More Fun With Build Sheets

I was going to reply to your request for info from anyone who found the build sheet in their ’94-’04 Mustang, but I forgot all about it. I just got my October issue and the letter from Jim Finley in Late-Model Corral reminded me. Better late than never.

I have a True Blue ’01 Cobra convertible and I saw the build sheet sticking out from the bumper foam, just as Mr. Finley did on his Cobra. Unfortunately, it ripped as I tried to get it out and part of it is still in there. The part I got out is water damaged, so what is left in there is probably in rough shape, even though the car has rarely been driven in the rain in the six years that I have had it. I would have to take the bumper cover off to get it out and I have just never done it. I guess this proves that at least some of the ’94-’04 Mustangs have build sheets somewhere in or on them.

It is apparent by the replies we’ve received since that initial reader question some months ago that, yes, ’94-’04 Mustangs generally have a build sheet still on the car somewhere. From the readers who have written us, it seems they are most commonly found between the bumper support and front or rear fascia, though we have heard of under the carpet and above the fuel tank as well. The real question remains: Did the ’05 and up Mustangs still get build sheets left on the car somewhere? We’re going to lean towards “no” on that one until we get reader/owner proof showing otherwise. Keep up the investigation, readers!

Keeping it Real

My husband has a ’08 Mustang GT/CS. He recently attended a show and someone told him that he should have a certificate of authenticity. We ordered one per the response you wrote in regards to the paperwork in a past Late-Model Corral column. While the certificate is nice to display with the car, the guy also said there were rules—things we can’t change, etc.—to keep the GT/CS authentic. Can you elaborate on this and where can we find these guidelines?

We believe your fellow show goer was referring to the Mustang Club of America’s judging rules for authenticity, available for each year of Mustang including sub-models like Mach 1, Shelby, Bullitt, and so forth. Mustang owners use these guidelines as a way to either restore a Mustang to bring it back to original or for a currently correct car to ensure it is maintained as such with the correct service parts, etc. What your husband has to decide on is whether he wants to keep his GT/CS completely stock and correct, or is he looking to modify the GT/CS for performance, handling, and aesthetics. The MCA does have modified judging classes that a GT/CS could be placed in, so whether he keeps the Mustang completely stock or modifies it, he can still show the car in MCA judged events. For more information on judging classes, authenticity guidelines, and the like have your husband check out the MCA website at
