I guess you taking about the Satin Alloy trim on a 78 Bezel right. It depends how it looks, if it yellowed, most easy to fix. The gouges harder if more then 1-1.5mm deep. Light scratches 1-1.5mm any thing deeper start getting hard. I would not try any thing deeper then 2mm. That been said I would sand with 2000 grit or higher, wet and dry you have to judge course you may need. You will have to see if the it looks like it may be biting to much sand to the longest sides (left and right) most of the time un less you can't. Most of the finish alloy has a fine etching on them. You may have to make small finger bocks help sand make a better job. I have not worked on the any 78 alloy Bezel yet but have worked on 2/84 fake alloy super thin plate painted plastic I came out not bad one not as good because gouges were more then 2 mm deep. I hope this helps you.
