I have used the Rustoleum version on several occasions with good results. One thing to experiment with first though is the orientation of the surface being painted. I found the "hammered" finish of the Rustoleum to work far better on a horizontal surface rather than on a vertical edge for example. The same could be true for wrinkled finished.
Also, if you search the net, various people have made paint wrinkle either by hitting it with a heat gun or a little lacquer over the enamel. You'd have to experiment with those to get the right effect.
