You must have got a bad Triade, my two Triade 250's still look as good as the day I bought them. No rattles, leather and Ostrich are great.
The only mods I've ever had that had paint come off was one of my VT133's. I had no problem with that because it's my work mods and took a beating. It's mostly the Black on the bottom (a little on the side as well).
With those types of battery doors (VT133, Therion, Finder, Triade), if I notice they are a little loose I give them a little squeeze when they off the mods.
Here's a few pictures I just took.

PS I'm in no way ripping the VT133. As you probably know my VT133's have been some of my all time favorite mods. I used the living crap out of that mod. It still works as good as the day I bought it.
Cheers,
Steve
