  After creating the trim path

  1. Make a new White Solid(you can choose any color that you want).
  2. Create a Circular Mask.
  3. Press T to reveal Opacity. Now hold Alt/Optn and click on Opacity.
  Create an express say wiggle(20,40.
  4. Twirl Down Contents>Shape 1>Path 1. Select Path and press “Cntl/Cmnd +C”.
  5. Select the White Solid. Press P and then “Cntrl/Cmnd + V” to past the path keyframes.

  Here is an example:

  You can also create the same effect using Stroke Effect(Generate>Stroke).
