ROTFLMHO!!
It amazes me that people have carpeting in their workrooms—of course, some may have no other choice. I've spilled too much solvent, paint, and glue—usually in disasterous ways (The phone or doorbell rings just as you start to decant some lacquer thinner. Startled, you spread lacquer thinner to the ceiling.)—to even consider it. And then, there's the carpet monster.
There is a solution that may save your rug, and your parts. Office supply stores carry heavy, clear vinyl floor mats that go over carpet to make it easier to roll desk chairs and protect the carpet from severe wear in those areas. Putting one of these under your work area will help starve the carpet monster, and protect the carpet from the slings and solvent of outrageous modeling. Not to mention, protecting your damage deposit if you are a renter.
