body work question

Hey all
Stripped my car down to metal and have several of different opinions
Should I put it in epoxy or etching primer b4 body work??? or primer then
start with the filler? Should I use epoxy or etching which is best?
this will be a weekend driver will not see any bad weather
Sorry for such a newbie question.
Thanks in advance for any help

Here's an quick summary of what my research has turned up...
1) no etch
A) bondo on metal then epoxy then high build blocking primer then sealer&paint
or
B) epoxy on metal followed by bondo then high build then sealer&paint.

Epoxy over freshly prepped bare steel, then body filler once the epoxy has cured. Sand the epoxy with 80 grit prior to applying filler. Etch primer is not to be used under bodyfiller!

Thanks guys for all your help
I have done repairs to my cars b4 but never whole car to metal
I at least want to try and start out right
Thanks again
