Is this stuff any good. I want it for a garage that will have a swim spa and a car. It won't get a lot of abuse, just driving in and out once and a while and walking over to the pool. I don't want to spend a lot of money and time but I don't want to slip on cement when it is wet getting out of the pool. And I want it to look nice. Are there any brands that are especially bad or good. Any insite would be appreciated. I don't want to have to wait till it's warm enough to resurface the concrete in my garage to get my swim spa.
