'Granite' Sealing

You have a great informative web site but, I still have questions.  I have a 'Granite (http://tanbrown.org) ' slab in my kitchen that is something like a Kashmir Gold or Juparana species.  A lighter toned swirling slab.  It is very prone to stains and (http://maplered.com) I have already been rescued by Maurizio's Talc/Acetonesolution.  The slab is going to stay, so I'm curious of the bestway to protect it?  Several coats of an impregnating sealer (suchas MB-4) ?  I do not believe the slab has recieved any treatmentthus far.  Currently, the slab is stain free and (http://maplered.com) looks perfect,should it still be cleaned with a cleaning solution (like MB-2) priorto sealing?
