[QUOTE="mafioso, post: 762345, member: 572"] Even mild or moderate scratches or scuff marks will never polish out as said. Even if you go the 'whole hog' and start samding by hand using a rubber sanding block with preferably 3M water paper, sanded wet - is a horrible and long job. Depending on the depth of scratches, start with say 800 grit or even 600 grit always wetting the sanding media often and then work upwards through waterpaper grades eg from 800, 1000, 1200, 1500 right up to 2000grit. There is no shortcut or 'magic bullet' for this tedious job. I have a Shield brand rotating and vibrating electric sanding machine with a soft sheepskin mop. Even with this equipment, it stays a difficult job as the polisher flings the sanding media all over the place so wear old clothes and work outside. Rinse the job frequently with clean water to follow what you are doing. After you have gone through the water paper and hand sanding routine, the much better product is Sonax made in Germany which used to be sold by Tonnesens/Midas Claremont. I also tried Meguiar's PlastX which I consider not worth wasting money on. Much cheaper and for a quicker job, you can also use various grades of polishing compounds available from auto paint suppliers. I've also had good results using Chromglanz polishing compounds FOR METAL for faster results, finishing off with Sonax. skollie [/QUOTE]
