...mukwah, I did something that is somewhat in reverse of your needs. My grandson wanted to highlight in white the etchings on his M&P 15-22 that I gave him last summer. I wasn't too hot on the idea, but, heck, it's his rifle. So, after a lot of begging I agreed to give it a try...having never done this before. Searching the Internet surfaced a vid that I considered perfect for the job. I followed this guy's instructions (he's really good) to the letter and the final result is as if it was factory applied. You might consider this approach, but use black nail polish, rather than white. Even if it dosen't match the bluing perfectly, the highlighting won't be so harsh. In fact, it would probably appear to be the factory method to slightly distinguish their logo and other info.

The alternative is to contact Taurus technical support and determine if they have any suggestions regarding removing the white inlay.
Just a couple of thoughts.

...btw, several of us have found nail polish to be pretty tough against normal chemicals used to clean our guns. The key is to use nothing that contains acetone that will attack the nail polish...
