It depends on how well you prep the surface. If you don't clean it very well or sandblast then the paint will easily start falling off in spots.
When I painted mine, the nooks and crannies that I couldn't easily get to with my wire wheel began flaking within a month. The broad areas that I did clean well haven't changed in over a year. I ended up buying a stock heat shield off of someone recently and painted it black. I like looking at it a lot more than the bare manifold, + my PCV line isn't cooking anymore.
As far as coatings go, Jet Hot is definitely where it's at but it's more expensive than paint and takes time, but you don't buy Jet Hot just for looks. Conversely high temp paint does nothing to retain heat either.
