I'm not sure about Rustoleum, but with most high quality industrial paints, 
there is an optimal coating thickness. If it's too thin it won't flow out and 
seal properly, but if it's too thick it loses flexibility and will be more 
likely to flake off the surface if the surface flexes or expands/contracts with 
temp changes.

One of the standard tests for this is to prep and paint a sample plate, let it 
cure properly, score it with a razor blade, and bend it 180 degrees around a 
pencil. It should not separate from the substrate, even at the score marks.
