As an alternative to epoxies, if you are looking for a coating that has a solid warranty, then look for a company in your neighbourhood that applies "Flexmar" it comes with a 15 year warranty on peeling, flaking and chipping. Its an amazing product... now it does cost a pile more then epoxy... but 15 years is a lot of peace of mind.
