Sanding Grit Theory
Thinking about skipping grits when sanding? Think again.
The theory of sanding if to replace one set of scratch marks with another set of finer scratches. Well, sort of.
You're not really saving much time if you use only 1st, 3rd and 5th gears in your car (assuming a non-automatic of course) and you're placing needless wear and tear on the car. Think of how effective and long your care will last if you only used 2nd and 4th gears.
Where to buy
If you are tired of using mediocre sanding paper, discs and belts that you find at hardware stores, and you're ready to move up to professional abrasives, go to Klingspor's or their Woodworking Shop. The difference is very noticable.
