Encrusted Tail Fins

Our rocket car is the fastest thing on the flats! So fast that ... I'm afraid friction is going to tear it apart!

To prevent that I need to create a composite to coat the car's moving parts. It must be hard but not brittle, and must be resistant to salt corrosion, or time spent on the Shimmering Flats will eat it away.

Have you heard of the Vile Reef, <name>? It's off the coast of Stranglethorn Vale. Saltscale murlocs live there, and their tail fins are a crucial ingredient of my composite.

Do you have the tail fins? If I can't protect our car from its own speed, then it won't last long in these races.

Thank you, <name>! After I grind these down and fuse them with a few other ingredients, the composite will be ready. And after that, the car will be safe from its own speed.

Safe, as long as it doesn't hit anything...
