No need to go with super spreadable TIM, or be too fussy about the amount used.
It's through my own testing that I've found that the pigeon poop TIM works the best in between 2 lapped surfaces.
The different TIM's I've tried were, AS5, ICD7, OCZ freeze and some generic pigeon poop. There was a difference between the thicker pastes and the pigeon poop. Granted, not a whole helluva lot, but it was there. Not to mention, there's no cure time required.
As for the amount, well that matters too. Of course, it matters on what socket you're using this on, as some sockets wont be able to apply as much pressure as others.
FWIW, my findings were on AMD CPUs'.

Now if he got a custom loop or even a decent kit and still wasn't happy with his temps he could attempt the lapping, but until then lapping is a last resort imo.
Though I destroy a lot of my items, so voiding the warranty is something I can't see myself doing.
To each their own.
Lapping, even for a "crappy" air cooler, if done correctly, will
improve temps by quite a bit.
After lapping my x3 720 and running my lapped Big Typhoon, it dropped both idle and load temps considerably.
On my 939 rigs, I was able to extract 200 MHz more simply because it was lapped.
