This sounds daft but you can avoid dents like that by being really fussy where you leave your car. One irritating element is the number of people who will happily drag their trolley between cars when they have about 1/2" on either side. To stop that I park right across on the far side of the car park away from the supermarket. Have a go at the dent yourself. Since it was caused by a trolley it's probably small and quite steep-sided, so pulling it out won't work. You might be able to gain access to the inside of the panel; if you can, take a piece of pine batten about 6" long, round the end slightly and see if you can push it out a little without raising the area above the level of the surrounding panel. Use a steady push and slide rather than getting rough with it. Apply filler-paste, and leave it alone for a couple of days. Then take medium fine wet & dry, and a margarine container of water. Now this is the important bit; don't hold the paper in your fingers. Wrap it round a little piece of hardwood so you are presenting a flat to the dent. Dip in the water and gently wear away the top of the filler. Keep it wet and do more looking than sanding. Test it with your finger a lot. When you come to retouch your metallic paint, don't put several layers of the metallic on. If you look, you'll find that the undercoats are of the plain colour and the metallic has been added as a top layer only. Take your time and don't expect it to disappear completely. You know where it was but anyone else probably wouldn't see it for ages.
Best Mike.
