I heard someone back in the bus said its possible to remove scratches in the body of vehicle just using the toothpaste.Is that true?
Toothpaste is basically calcium carbonate a coarse material like a sand paper. i have used it to clean the car headlamp and rear view mirror.It gets ultra clean.though I have not used it on any painted surface by myself but some articles suggest that it can remove minor scratches from paint.Refer this
According to Ryan Dube of MakeUseOf, toothpaste is a sanding tool. It's like a lighter, softer form of sandpaper. As you gently rub toothpaste onto a slick surface, it "catches" on any imperfections that exist and softly sands them away, wearing away the uneven surface problems and polishing the surface clean.
I think you could give it a try at a small surface of your car no harm at it.
