I'm farming Rust Duramboros right now, using Zinogre armor and the Liquid Storm switch axe. I've found that pitfall trapping him and setting up two large barrel bombs at his humps is a great way to shorten the fight, so I always bring one pitfall trap and some bombs of my own and then pick up the supply ones from the box later for two sets. Then there's also the opening to put him to sleep with the throwing knives from the supply box, leaving him open for the spare bombs on his head.

Beyond that, take advantage of the fact that his tail club doesn't reflect your blows if you have blue sharpness or higher. That's a huge help that makes him a lot easier to get parts from than the standard Duramboros.

Additionally, if you can time the flash bomb right while he's spinning, you can knock him onto his side for a while and leave his humps open for attack.
