1) use a cleaner first and see how bad it is. you can use a plastic scratch remover or even toothpaste to sort of dull the scratch. but be careful no to over do it you will start to make sort of a shiny area that will look worse than the scratch. you can also try using a hair drier to slightly raise heat of vinyl and try and rub out the scratch. vinyl will take a lot of heat so dont be to afraid just dont melt the glue holding vinyl to the door panel. good luck and let us know the results.

I had a similar type scratch and it did a nice job of blending it with the surrounding area.

Natural Look is water based but it seems to last better than others I have used.
I have also used the Prestone vinyl repair kit to fix some scratches and tears.
It works as long as you get the color matched just right. I also use a propane torch to heat the metal ironing tool instead of an electric iron because it is faster and the product seems to respond better to the higher heat. You don't want the tool so hot that it burns the paper though.
2 C) Do nothing... As you heat the area, the scratch will smooth itself out. Keep the gun moving, about 2-3 inches away from the pannel, concentrating on the scratch. What happens is as the plastic heats, the rough edges or the scratch get soft and, as I mentioned, smooth themselves out. Let it cool without touching it and procede as normal with your chosen dressing. I've had to use this method on many pre-production mock-ups and prototypes.

Ultimate Protectant probably does a better job of this than anything else. Obviously you can't really polish out a scratch on a textured vinyl surface, but you can conceal them a bit. UP seems to do a very good job of this.
