My new bathroom vanity top get dark areas that appear to be wet but are not. I believe this is because water is being absorbed and that I need to seal it. The darkness eventually goes away after time. Do you agree that the vanit top should be sealed and what is the best type of sealer to use, any specific recommendations would be helpful!
Are there any general warnings or recommendations as I am not really familiar with this process
Thank you!

Even brand new granite surfaces get sealed by professional installers. Was your's installed by a pro or by you. How to Seal a Granite Countertop | eHow.com

The granite came with the vanity already installed, purchased online. I can assume it was not sealed due to darkness after water. Just looking for brand recommendations for quality products.

Make dry and clean of your vanitytop before using the sealer. In our factory, we need to put them under the sunshine to make the granite vanitytop dry enough.
