I've shown you how Natsu's attack against Rogue clearly expanded to engulf Motherglare in the anime. That's the way the animators saw the scene, and that's the way I see it. Atlas Flame never made an attack after boosting Natsu.
All that's said about dragon scales is that they are super hard. There is absolutely no mention of a special resistance to magic. That's something you made up. If you truly believe Zirconis' real element is the ability to make clothes disappear, then I guess he's immune to magic that makes clothes disappear. Doesn't change the fact that if the dragons are resistant to anything, it's only their element.
Beginning of the series Erza would blast a hole through Dorma Anim's chest the same way Natsu did. So would GMG Cobra. So would any character that has an attack stronger than Natsu's sword horn boosted by Wendy's roar. By the way, they used the exact same combo on Hades. Only instead of just Wendy's roar, it was an unision raid between Lucy and Wendy that boosted Natsu. Droma Anim actually has pretty poor durability.
Natsu was boosted by Atlas Flame's power, and this outweighs any injuries he received prior. Proof of this is in the fact that Rogue can no longer defeat Natsu with WSD Silk in their rematch. Also, Natsu was not the only dragon slayer fresh. Sting was unharmed during the GMG and had full power. Sting was arguably stronger than Edolas-arc Natsu. Sting could not do anything against his dragon too.
I'll end with this: Dorma Anim isn't an actual dragon and doesn't have dragon scales. It uses wizard canceller, which is a different material altogether. Wizard canceller makes you immune to magic, but its nowhere near as durable as actual dragon scales. When dragon scales fall off a living dragon and loses its power, it becomes weak enough to knit a scarf out of. Droma Anim is a lifeless machine. Any dragon scales you use to decorate its shell would have simply lost it's power long ago.
