I just wanted to know what is the best approach towards polishing large pieces of stainless steel auto trim. I have done some small pieces (around 1"x.0.5" in size) with good results, using sisal/ss/loose & black/green compounds.

When i try the same on larger pieces of trim however the results are not very good which i think is caused by poor technique. What i want to know is what is the right technique to use in polishing large pieces.

After hand sanding (to remove deep marks) i use black on a sisal wheel which leaves many finer scratches of its own. After this i use green compound on a spiral sewn wheel and buff at 90 degrees to the direction i did the last cut in. This removes most of the scratches left by the sisal buff, but leaves many of its own, which i find very hard to remove in the next step.

What i am stuck on is what should i be doing after this. Should i be cutting, or colouring with a loose wheel, and should it be in the same direction or 90 degrees to the cut made by the spiral sewn/green.

also

- does it matter which direction i apply the piece to the wheel when doing the first cut (ie: horizontal against the wheel motion, or vertical against the wheel motion)
- does each cut need to be done at 90 degrees to the last cut.
