Yes you use sandpaper. If you saw a shiny plastic, it was probably a hard plastic sheet or glass they were using to ensure they were lapping on a flat surface. IE

heatsink level
sandpaper
glass sheet

That way the heatsink is lapped flat and level.

there are plenty of guides in the forums. basically, you get a flat object(most people like glass). put your sand paper on top of the glass, and sand the h/s or cpu flat. but first, put a razor blade against the h/s or cpu(whatever your lapping) and see if you can see light, if there is a gap between the 2 you will see light. if there is a gap, you should lap. start off with like 400 grit sand paper and keep moving up in grit until its flat. its alot of work, but most people see good results from it.

Not a waste of time at all. I lost 5-10C on my quad. Here is a great site for lapping kits. 6 shipped for a kit without glass, 12 shipped for a kit with a glass plate.

The owner is a really great guy as well. Fantastic customer service.

Just remember to keep lapping until you get to the copper plating. Gotta remove the nickle first, then concentrate on getting it level and flat.
