What do you guys charge for countertops? I have been at $200m2 ($20sf) for a long time, seems to work but I have a large commercial job I am bidding and was wondering how low I could go.  Usually I go 400 genisis (electroplated) dry, then 120r, 400r, 800r 1800r, then5x. I will stop ar 800r sometimes but I rather do a quick pass with the diamonds than have to go hard with the powder.
