- Use sanding pads (3M, Abralon, etc.), not sand paper.
- If you use sand paper, make sure it is waterproof, or things get ugly.
- Use water when you sand the ball. A manual flower pump is helpful to keep some water on the surface
- Do not use too much pressure.
- Sand a ball at least from 4 sides, or 6. The same applies to polish
- Use a tub for the spinner. Otherwise, things get messy. An old shirt is good, too...
Otherwise... go on, collect experience, learn and grow. It is not wrong to test your sanding procedure on an old ball, and then test it how it changes reaction on the lanes.
There's no magic to it, just treat your ball like a steak: when it is overdone, you can throw it away... so just stir gently and "control the heat" you put to it. Good luck.
