Sanding a 'beached' disc:

1) Wash the disc off to clean off any sand, dirt or salt. Then dry it off with a towel.

2) Choose a grit of sandpaper depending on how roughed up the disc is. (If it's really rough start with 600 or 800)

3) Rub the sand paper in a circular motion until the surface is smooth. (this takes some elbow grease!)

4) Go to the next sandpaper grade (If you started with 800 grit then go to 1200 next) and repeat step 3.

5) Repeat steps 3 & 4 until you've sanded the disc with 2000 grit sandpaper. The disc should feel smooth as silk with no rough spots.

That's it!

Here are a couple tips...

a. The sandpaper will last longer if it's wet when you use it.

b. Before moving to a higher grit be sure to check the disc surface for any rough spots that need extra work.

c. Don't forget to sand the inside rim.
