Well, I'm nearing completion on my first engine. So, I've been working hard at getting it looking nice. Sanding with ever finer grits (down to 1000), and then off to the buffing wheel. I start with tripoli compound on a spiral sewn wheel, and move to white polishing compound (sticks, not sure what it is) on a loose sewn wheel. All well and good. Shines up fairly nice. But, when I get to that last bit, I can't seem to get the streaks out. It's the last minute bit, when the light hits it just right. More or less pressure on the wheel, more or less compound applied, nothing seems to get rid of it. If I turn the part 90 degrees to the last buff, the streaks seem to go in that direction. So, it is micro scratches? What do I use to eliminate them? Parts are 360 brass and 6061 aluminum. Both exhibit the same hazing. Hints?
