I don't think acetal shines up too well. I've polished up Corian when I made some pens out of it and it polished up real nice, but Corian is quite a bit harder than acetal. I have some acetal so I'll spend some time and see if I can get it to shine. For the Corian, I started at 400 grit and went up to 1200 grit and then used the polishing compound.
