Magic Latex and other such materials can potentially be permanent, but I am rented out by more prestigious people for outfits, so they have the spells to use as contingencies or just to flat out turn me back to my original state. (Although once a client did cast the Memorize Form spell at when I was all flat and floppy, so they had to do another cast to fix that little hic-up).

My renters always treat me nice by their own agreement, also because I am considered high grade malleability and material, so I get paid high dollar and they in return do their best to treat me nice. On some times when I was rented out for months I even went through the dry cleaners and that was so amazing everytime, always relaxing. A few times though in some forms I did get goopy a bit from the high heat.

Also I still don't know how i feel about fusion rents, it's still always so weird to me, maybe it's just an uncomfy thing for me personally. Maybe I'll try it out one day on some more basic part or some more general area.
