Body filler used on automotive repair. Hardens with a catalyst.

Technically a brand name, it has come to discribe any type of plastic body filler used for automotive body repair. Moslty talc, and is mixed with cream hardener for it to dry.
Always dries faster than you want it to, especially in hot & dry weather. But once you can work with it, that's no problem, it actualy saves time in the body shop.
There is no shame in using it when using it correctly. In a body shop, it should be no more than 1/8 inch thick. It's the redneck morons who slap 12 gallons of it right over paint and rust, then spend as mucn time as it would have taken to do it right to sculpt the shit with an artist's touch to mimic the appearance of actual bodywork. But bondo not put on correctly will not last forever, and this crap bodywork will eventually crack and fall off and make whatever sucker baught the car want to scream and gouge his own eyes out.

Bondo is someone who firmly believes that sadness runs through his genes.
