I roll with brilliant 2. I start with 100, bump to 220, 400, 600, and stop sanding at 800. I switch to mirca screen at 600 then to platin 800. After 800 I switch to polish mode and use a paste. Technique in sanding is the most important thing. At class I learned to sand in three directions. One pass left to right with a half to one third overlap at about an inch a second, the next pass front to back same process, the third pass in a circular motion 6 to 8 inches in a clockwise motion.
Polishing I use the felt pads. I have not yet found a polish that I'm in love with. Originally I was taught to use a rouge but have seen and used boat polish and "pen" makers paste. When polishing, heat is very important, or the lack there of. Depending on the polish you may need a spray bottle of water to keep the surface cool.
A word to the wise, time spent on early steps is very important. Sanding at 100, it is important to look for and remove all surface scratches. You will find at later stages things you missed earlier if you are not careful. One of the other more important things to be aware of of is the removal of dust created by the proceeding stage. A clean wet rag is very useful .
Like all things we do in the practice of our craft, process in everything. Consistency, and discipline to process will result in a superior product.
