Be aware that the concrete will no longer absorb puddles, like when you
drive a wet (or snowy) car into the garage. So the puddles will remain
for a long time.

Before you even consider a top coating, you MUST perform a water vapor
transmission test. Do a google search for calcium chloride test kits.
You will need 3 of them placed around the garage. They come with a
canister of calcium chloride and sealing plastic domes. After surface
prep, you put the canister on the concrete and apply the dome. You
remove it after 72 hours, seal the canister and mail it into the
testing lab. That will tell you how much water vapor your concrete is
transmitting. If it's more than 3lbs per day, epoxy is out of the
question.

The plastic film test that most epoxy companies recommend is a
worthless test.

Bottom line is: the majority of users say their epoxy comes off the
floor, expecially where the tires rest. This happens even when it's
professionall applied and the concrete is acid etched. Epoxy is NOT
the cure-all the manufacturers would have you believe.

Well, thanks everyone.

After reading the responses, I have decided:

-- Paint with epoxy;
-- Don't paint with epoxy;
-- Paint with Thompson's Water Sealer;
-- Or not;
-- Stain with concrete stain;
-- Or not;
-- Run a water vapor test before painting.

Think I'll leave the concrete bare and let whatever happens happen.

ultimately thats the least costly approach, BUT sealing with thompsons
still leaves the bare concrete look, will darken the appearance a
little, but prevent oil and grease absorbing into the concrete..
