Depends on the colour.I had two scuffs on each side of by bumper (black).Been there since i had the car.A quick clean of the area, flat back with a bit of wet & dry.Once smooth i scotched the area pencil'ed on some base paint then covered with 2k clearcoat,followed by a bit of fade out thinner.Took all of 10 min to spray.Left it for 24h then a quick flat with 2000 W&D and a polish, it was as good as new

Some companys like chip's away will do smart repairs like this.You can do it with Red as long as the paint has'nt faded too much.If it's silver take it to the bodyshop

If lot's of stone chips it will be panel spray and poss surrounding area depending on colour.
