Hint: Meltdown:
Rather than going through all four chambers, only go through the first one. Retrieve coolant, bring it back, and put it on the ground near Dr. Hamilton. Next, fly back into the labs three more times, repeating this strategy. You can do the meltdown much faster this way.

Hint: The Comet move:
Start flying by very gently pressing R. Then, start Speeding Bullet (press R hard). Immediately before you start Speeding Bullet, launch a Heat Blast (press Y while still flying and Y again when you just held R harder). Do not change your route of flight after this is done. If done correctly, Superman should look like a red comet. This move can be used very effectively against Bosses. It does more damage than Speeding Bullet and Stuns... However, it cannot throw your foe away like Speeding Bullet.
