ProCaliber Products Foam Acrylic Polish & Scratch Removal Light Sanding Block

will it work on corian?

would it fix /polish scratches on gray granite countertop? The scratch is not deep and not visible if wet.

Silly Question I think... you just use as is for each side... or do you need to remove the white piece from the grey backing or peel something back?

This is very small...How large of an an area can you do before it is worn out? Is it the same as those $1 finger nail buffers?
