Custom PONG Build Part 14, Ball Nose

The ping pong ball nose cone had a deep, noticeable seam.
The kit ball is on the left.

I tried to fill it with a bead of medium CA.
After it dried it melted through the ball plastic a bit. After sanding it smooth it thinned the (already thin) wall of the ball.
I didn't want to use it now.

I've got a few new ping pong balls in my spare parts box.
The ball on the right was one of six bought at a sporting goods store.
It is smooth with no real seams.
Only one ball out of the six had a seam, not as wide as the one in the PONG kit.
