There is polyester and nylon carpet, which vary in price.

It’s too much of a ‘pastel’ color which makes me think of little old ladies wearing polyester pants.

Now they have a cordless polyester fabric blind, but it doesn't have slats. 

Many clothes are polyester/synthetic that do not readily support mold growth. 

., dressed myself up in Polyester slacks and silk blouses, panty house (that were required), and high heeled shoes.

The fourth layer is usually made up of polyester material which can resist vapor from the subfloor and balance other 3 layers.

Examples such as the VCR machine, 8 Track tapes, polyester Leisure Suits ( Hmmm...that was random), to name a few.

fix-it-all (joint compound with some additives) is not suitable for exterior at allYes it will wick in water as the paint deteriorates, and cause more rot, and keeping a good coat of paint on it won't be enough long-term in many/most climates.bondo (polyester auto body resin) is a cheap-ish "alternative", although harder to get detail work just right and not really all that suitable anyway (maybe ok with a good epoxy / primer, perhaps?).

. $1,500.I know the carpet needs to be replaced but is nylon good enough with a nice 8 lb. pad or do I need to go polyester?

Note on carpet choice...stay away from polyester, it will show traffic patterns quickly.
