what the difference between 1000 grit and 1000 polished finish on a bowling ball
Using a 4000 Abralon pad on a polished bowling ball will reduce its shine and create a finer surface texture, resulting in increased friction with the lane. This can enhance traction, especially on medium to heavy oil patterns, allowing for better hook potential. However, it may also reduce the ball’s length and backend reaction, so it's essential to consider the desired performance characteristics when altering the surface.
Of course have you ever seen a bullet that is brass or copper . Brass causes much less fouling of the lands and grooves
The purpose is that when the ball is thrown the polished side gets less friction in comparision with the other side so the ball swings
The surface of the bowling ball is usually sanded or polished during manufacturing or by the proshop operator. It relates to the grit of wet sandpaper or polish.
