Good stuff. It's Shure rating is 37, so very similar to the stock rubber. Should work pretty well, just hope it stays put! Also available in black for others considering this.
The datasheet says shrinkage can be as much as 10%, so you might need to top up any gaps that form over time.
I also considered urethane windscreen glue but that's around 55 Shure, so probably too stiff, but it would stick well!
