Performance Choice Manifold Dressing???

[JJS]

Can anyone out there tell me their experiences with "Performance Choice Manifold Dressing?" The advertisement I read states that it cures as you run your motor. I don't want to use something that doesn't cure, like Kalex (sp?), as I heard that stuff gets all over the engine compartment. I would like to dress up those exhaust manifolds, though. Thanks in advance for any advice.

I used Calyx and it still looks great.
