I inspected a white (ice) granite counter top. It had been installed the month before. It has 

a obvious large yellow stain that is resin. The rest of the slab has a light yellow film over it. Except

along the edges where it was bull nosed. I tested it with epoxy stripper and honing powders and could not remove it.

The big puzzle is that it sat in the slab yard exposed to the sun for 7 months and did not yellow

except in a small 6 inch x 6 inch area.

Any ideas as to why. I know the the owners of the slab yard and they showed me several other

slabs sitting in the sun of the same granite, same shipment. There was no yellowing overall

just a couple of small spots.
