Id like to strip the sealer polish on my Granite (http://tanbrown.org) Counter (http://GialloFiorito.com) tops., stain them a different color( from tan to dark bluish black color). can this be done? what do I use to strip sealer. the problem is, the busy design on the existing tan color Granite (http://tanbrown.org) is making my eye sight go bad. I need something not so busy on the eye. thanks!
