Do any of you know of any treatment, sealer, coating etc that can prevent marble from etching or at least minimize the etching? Will crystalization help?

I know that is hard to prevent the chemical reaction from damaging the stone but I remember that John mentioned some new product developed for restaurant or hotel industry that supposed to minimize the etching.

I have a customer that supplier sold her quartzite material (ivory bamboo) for a kitchen countertop. it turned that it is a marble, a very sensitive marble. The only way I can get good finish with out burning this stone is to hone to 1500 and polish with Stone Tech 3000 powder. It is job security for me (already 2 trips within 2 months) but I am growing tired of listening of the same story again and again. The supplier doesn't want to do anything and customer is stuck with 24'x6' beautiful slab that etches like crazy.
