Still have the stock radiator? If so, check the top of the radiator (black plastic tank) for cracks. The OEM radiators are notorious for cracking at that plastic tank and will spray coolant everywhere.
Did you try cleaning the engine bay to get rid of all the coolant? If not, you should wash down the engine bay, refill the coolant, start the car (let it warm up), rev it, and look for a leak.
