I never said it would work good, I was just trying to explain the theory behind why it could work.

You have no way of knowing the thermal conductivity of the dried film. You are making the assumption that this junk has a very low thermal conductivity, and since this stuff is designed to go on heat sinks, I would think the engineers behind it would be smarter than that. If the thermal conductivity of the dried film is more than the conductivity of your aluminum fins on your heatsink, it would increase
the amount of convection by being easier to get the heat into the air. (Picture fins made out of silver instead of aluminum.)
Radiation is worse than convection and conduction in certain very limited circumstances, but not as a general rule. It depends where the heat is coming from, going to, what material it is traveling through, air currents, ect.
I am glad to see a company finally trying to think outside the box for once.
