Glasurit is the king of the hill as far as paints go. As I understand it, Sikkens is close behind.

No one has said the obvious, but all this expensive paint won't look good unless the painter knows how to use it. Prep, prep, prep, prep, and more prep....... Oh, and never just buy enough. Buy one or two gallons more than you think you will need -- and buy all your gallons at the same time, don't go back later, that's a bad plan. But before you go hog wild on buying gallons of paint, make sure you do some spray outs with quarts to make sure the color is there where you want it. Don't ask me why I know this........... Your wallet will cry, but you will cry harder later if you don't have extra for later. Same goes for the other paint chemicals. Should have some unopened cans so you can mix it all up later. Just because you can buy the stuff now doesn't mean you will be able to in the future.

Best of luck on your project!!!!!
