filler right on the metal.just make sure the rust is dead...or all gone, use picklex 20 if it's bad..you can sand the whole thing, use picklex on the bare metal and take your time doing bodywork..

Most etch primers are acid based and don't mix with body fillers.
You can use epoxy primer and filler on that, but filler on bare sanded
metal is fine.
Use epoxy on bare metal, it's compatible with everything and
does a much better job.

Filler wont stick to etching primer.....
A lot of us feel epoxy first then filler is the best way to go for a lot of reasons
But I think everyone agrees epoxy is the way to go
Not all epoxies are the same do a little research before you buy one

etch is only good for leaving something in primer to work on later and then sand it all off later. Nothing likes to stick to etch including fillers, primers, and paints. I think slick sand says it's ok but it's nothing I'd do. Works great for protecting metal from the elements and it's cheap.
