Well, it is used for fixing cracks.
A black-market butt-enhancement "practitioner" is injecting New Jersey backsides with household caulk and other hazardous materials, according to New Jersey health officials who have alerted New York authorities to the rear and present danger.
Six Newark-area women in the last two months have been hospitalized with infections caused by injections of "a variety of unknown materials," said New Jersey Health Department epidemiologist Dr. Tina Tan.
Officials said they believe the injected mixture includes silicone, petroleum jelly and hardware-grade caulk.
After botched efforts to plump their rear ends like naturally well-endowed celebs such as Kim Kardashian, the victim's derrieres resembled "moonscapes" filled with lumps and craters, said a hospital source.
"What we've been hearing from the hospitals is that these women are presented with deep tissue infections and skin infections. Abscesses form in some cases," said Dr. Tan.
According to hospital sources, the six women were all from the Dominican Republic. The injection "treatments" occurred in hotels around the Newark area, the hospital source said.
The serial quack could face criminal charges of practicing medicine without a license.
