I want to paint my garage floor and I will need enough for about 1,200 sq ft. I painted a garage once using some water based stuff from wal-mart and it had a big problem w/ hot tire pick up (eventhough it claimed to "resist" that). I've heard that the kit you can buy at home depot works well but it is $90 and I'd need two. Just wondering if anyone's had good luck with a bulk industrial product that might save me a few $$$
