Hmmm, Porcelanosa used to factory seal ALL of their porcelain. For years it was the only one I cold install without sealing and know it wouldn't stain.
I was told that all polishing opens up pores on porcelain (and stone too) but particularly cheap porcelain would be more prone to open pores than higher grade, denser porcelain.
