I've had the car wash, protectant and tire shine for a few months now (I got a gallon of each as part of a internet deal a while back). Here are my thoughts:
Optimum Car Wash
Slick, good suds, and smells good. It cleans fairly well, though I generally like it on cars that aren't too dirty.
Optimum Protectant Plus
Pretty thin, low sheen to matte finish. Doesn't make the plastic slippery (at least on my running boards). Ok on leather (I prefer a deeper look), but no testing on the claims of being able to "repel dust"
Optimum Tire Shine
Also thin in consistency, it has a low sheen that is nice (again, I prefer something a little deeper). Durability was about average for me.
All three are fine products, but the protectant and tire shine simply didn't have the "look" that I prefer.
