first off I isolate just the faces of the text if there are bevels.
in a seperate comp I would create 5 or 6 solids. On each of the solids use the pen matte tool and cut various vertical and angled shapes and feather them a lot. Then animate each one from left to right or whatever your preference is. Vary their shapes and speed to get unique highlites. Use the matte of the letters faces to cut out the highlites and place that comp on top of your text.
You can change the hilites up by editing the one comp add colors to the
hightlites or whatever. I do this for BASIC ‘sheen’ hilights.
If you isolate the faces of the letters you can try all kinds of plugins as well.
