concrete doesn't sweat due to the lime, it sweats because it is a big cold mass. Airborne moisture will also condensate if the air is warmer and the slab is colder.
I put 4 X 8 sheets of styrofoam insulation on the floor under the car for a thermal block. It seems to help. But, I also don't have a lift.
I don't know what else you asked earlier, but, is the garage insulated and relatively draft free? South facing windows unblocked?
