I like Meguiar's #7 and also Chemical Guys Ultimate Glaze for the paint.
Interior I use warm soapy water (Dawn or Joy) on the vinyl with a soft nail or hand brush.
Fabric seats I use any mild cleaner you can get from the grocery store.
Sometimes even a magic eraser on certain areas.

Spray away aerosol non ammonia glass cleaner and a tooth brush is what I used on the interior in the 69 Z I got from you tony... BEAUTIFUL original door panels and seats.

Remember the terrific job Supercar Workshop did on the Houndstooth Dana that was found in Hawaii? I think they used Simple Green on the seats. (or maybe it was Green Clean) Looked new when they were done!

Thanks for the ideas guys!
