Grant that floor looks great. Im a member at garagejournal.com and read all the threads on epoxy and wanted to do one but it didnt fit in the budget. My garage is 900 sq ft and would of cost over a grand.
So i went the cheap route and bought some .79c a sq ft laminate flooring. With the vapor barrier and edging i spent around 400$.
Seems to be holding up fine, only been 6 months though.
