I've had good luck removing the insert and boiling it. then using a fat dowel to push it flat while it cooled. I had to do this on my Lightning since the inserts were rising out of the field at both ends.
I suspended it in a strainer in the boiling water so it wasn't sitting in the bottom of the pot.

Quoted from CaptainNeo:the only thing you can do to save cupped inserts is have it clearcoated. I've done tons of EM's and fill them in to get that glass like feel and play again. Some inserts are cupped so bad, if you sand them flat, the outside edge will be so thing, you'll end up ruining the insert. Better off leveling through restoration clearcoat. But don't do it with varathane, because if you put that much varathane on, your colors will look extremely washed out. Every level of varathane you use, reduces the colors drastically.
