Mine has been down for almost 4 years now with zero problems. It's starting to get some wear marks from the tires but other than that still going good. Wish I had top coated it with the clear but didn't know they had it back then. I used the "retail" Rustoleum gray.

Think it's just like detailing..... All in the prep! 10 hours of, power wash, 2 times Simple Green and rinsing, lots of rinsing. Used a new push broom to scrub with, hand scrubbed a few spots. My 2 car garage was 17 years old when I did it and pretty clean for it's age.

And make sure you rinise, rinse after using the etch stuff.
