This is a typical weakness for hellborn/mania. Without more information from you, I can generalize by saying that a hybrid fire/explosion build seems to work the best. Explosion will out-weight corrosion on armor due to the buffs from skill points, mods and relics. The co-efficient from corrosion is 1.75x damage on armor but it can only be boosted by Krieg with a mod.

Given equal damage boost from mods to both corrosive and explosive, the corrosive also has a 75% natural boost. Strip the Flesh, Blood Bath and a Crunch class mod can boost way over 75%.

To go distance kill, a KerBlaster can be used but an Ogre is much better. Along with homing grenades, the explosive damage on a slagged armor enemy will go a long way.

This is my build (look at the bottom for OP7 update).

Having help, of course, can help.
