When doing this make certain that the coating on the bottom of the unit itself is not compromised - I think it's supposed to be insulated from ground (the body of the car). Heat sink compound alone is not designed to do this. In the original installation of a unit the paste is held on by a thin layer of high-temp, thermally-conductive plastic; the bottom of the unit itself is coated with something (paint?). When cleaning off the compound from my spare, I went through this coating and I'm thinking about how to repair it.
