Thermal epoxy or Thermal grease and bolts? Answered

I am mounting 15 Cree LEDs to get an old overhead projector to work as a video projector. the only thing I am wondering is whether thermal epoxy is better to use than thermal grease with bolts and nuts attached to a heatsink. Do both have the same heat dissipation? What I am trying to do is still use the LEDs for use with other projects in case i need them for something else.

thermal grease and bolts should be fine; they were widely used for everything long before anyone had ever heard of "thermal epoxy."

Grease has another advantage, too--you can easily remove / replace the LED modules, if any develop problems...
