One more time. (accidentally posted this in a.b.p.w)

My gar^H^H^Hshop has several areas where the surface of the concrete is
failing. I'd like to repair it, if for no other reason than it makes
rolling tools around a pain. After Googling around, there appear to be
dozens of products that claim to repair a concrete surface. What I'd like
to know is if anyone has actually used a product for this purpose that they
were either happy or unhappy with?
