Trying to fill a hole with just body filler isn't going to cut it. I know. I tried this in 1980 on my 55 Chevy. Many years down the road you can see the ring of the trim holes where I filled with filler. Around 2010 when I was finishing a frame off resto on it, I welded small plugs (3/16") in the door trim and fender trim holes. Painted it in 2013 and now ten years later still good as new. The bad? Filler absorbs water and it's hard to coat that from the back side on many panels. Filler also shrinks over time. If you plan on painting and want it to look good, do it right so your paint can look good without showing deteriation around those quick filled holes.
