Subject: [sccpartners] granite counter top big crack near sink of course.

ok should i just fill it and polish and blend
or would there be a way to reinforce the area
without weakening or breaking it off.??
don't want to buy them a counter for a 500 dollar repair
not sure i should even do this one

Thanks
