Dear Karen:
Quite frankly I don't know what to tell you. I'm not familiar with that product at all. If it is strictly water-based, then chances are that the darkening of the stone is going to be only temporary; but if there are other ingredients of an oily or acrylic nature (like the name suggests), then it could be permanent. Therefore I can honestly tell you words of encouragement. The only ones who could are the folks at the customer service department of the manufacturer of the product. My best word of advice is for you to contact them and see what they have to say.
May I ask you now to please read and e-sign our Statement of Purpose at:

Ciao and good luck,
Mauri
