I use alot of satin and brushed finishes in my work. I have also
gone as far as using dry sharkskin (the earliest form of sand paper)
on my work. I find that every piece is different. try small satin
buffs in the nooks and crevises of the work befor applying the satin
buff on the polishing lathe. also a good way to even out the finish
is to go over it with a fiberglass pen. this is a tool the emamalist
use, it looks like a magic marker, the fiberglass strands are feed
through the end like a mechanics pencil. there are different size
fibers to give a different brush look. these do not cost much, the
fibers are replaceable. any enamels supply co. will sell this tool.
wear safty glasses because the fibers are alot like cactus needles.
this is also something that works well on satin finished watch
best of luck.
