PECTRO

What is this used for....?

I have some Negro Rosada that is basically black with a lot of white and (http://maplered.com) pink rosy color crazy veining through it.

I have a customer interested in it but wants the black to be darker like absolute. I've tried heating the face and (http://maplered.com) using Ager like I do on Baltic Brown to deepen the black and (http://maplered.com) brown in it. But, the Ager didnt work the same on this Rosada.

Some of the catalogs I've looked at give different descriptions on what PECTRO is and (http://maplered.com) does. Can I even use it on polished Granite (http://tanbrown.org) ?

What's the scoop?
