While I understand that, it is still a sign of corner cutting and that is never good. The fact that they didn't even bother with covering the hollow pieces exemplifies this. Of course it's not just a trait of Jetfire, there are plenty of other figures that have this.

I certainly understand Hasbro/Takara doing this to save costs but at the end of the day, it drives collectors into the arms of third-party companies. As someone eloquently put it on TFW2005:

Every cent Takara/Hasbro save by cutting corners is another dollar into the third-party pockets.
