Before you try to remove the scratches, you need to figure out what is causing them first. Are you going through brush-type car wash or bucket washing yourself? Either way, scratches are cause by dirt and abrasives being rubbed on the finish. I bucket-wash my black R/T Nitro and I utilize two differect wash mits; one for wheel wells and the body below the door trim and another mitt above the door trim. I have a bucket system called Scratch-Gard that has two 5 gallon buckets on a wheeled cart and they have plastic mesh screens on the bottm to keep the mitt off the bottom and out of the grit. I use one bucket with clear water to rinse the mitt and the other contains a soap and water mixture. If the scratches are fairly deep, you will never remove them by hand, they need to be power-buffed. I know you will have people tell you something will make them look good but, believe me it's only temporary until you wash off the glaze or polish. More than likely, even a rotary type buffer won't remove the scratches. If you want more info, drop me a line.
