Here is what the back of the tube says verbatim.
"Wash car first to remove loose dirt and fresh contaminants. Test on small, inconspicuous area first. Apply small amount of product, evenly to a cool surface (always in the shade), using a foam applicator or soft, clean, 100% cotton terry towel. Work one section at a time and let product dry before removing excess with a separate clean, 100% cotton, terry cloth towel, turning to a clean portion for the final wipe. Do not use on unpainted vinyl or rubber surfaces. For durable high gloss, immediately follow with an application of Maguiar's Gold Class Clear Coat Car Wax to enhance and protect the restored finish."
EDIT: And just to make sure we're all on the same page here. The tube is black. It says "Meguiar's" on the top of the tube (with the cap flat on my desk). Below that it says "Scratch" in all white capital letters with a big red X behind it. Right below the X it says "fine scratch and swirl remover". Below that it says that it "safely removes light scratches & swirls, oxidation & blemishes, and bonded contaminants".
