Body Filler Preferences

Hey Folks,

Going to start some body work, i.e. light damage to rear corner, and light surface rust. Been a while since I've done it, and back then (early 80s) "Bondo" was the filler of choice. But I'm wondering if any of the new options are better. Will be using it to smooth out body work, no holes or rust throughs. Would welcome suggestions anyone may have to share.

Thanks in advance,
Pat
