1) After attaching the sandpaper to a flat surface, do you move it across the cpu, or does the sandpaper stay stationary and the cpu is what you move over the sandpaper?
2) Do you go in the same direction for a little while, then the opposite way while using same grit? Or like back and forth? I know you should turn the CPU after a little bit too.
3) I know you're supposed to use soap and water or some lubricant, do you just put some directly on the sandpaper? Or like the back of the sandpaper and let it seep through to the other side? Also, if you're using water, the CPU is going to get wet isn't it? I found it surprising you could use water, do you just dry the CPU with a blow dryer or something afterwards?
