Good points.

Luckily I was able to find the cause of the rust problem. I sanded to
metal and of course applied fiberglass filler AFTER that.

The original work had failed in that the filler had cracked quite
badly. I could only assume rust had started. It had, though with very
little pitting.

I was hoping that the area around seam on fender well, that I sanded
to metal and primed with Tremclad, would accept filler. (there was
already lots of filler there) Apparantly it won't, but I can live with
asthetic flaws.

Having just sprayed a top coat on, I can say for sure take your time
sanding the filler.

I know that feeling the area is one thing, (it felt smooth), but
looking at it is another.

For a novice like me, I'd say get a good/proper light on your primer
coat and LOOK to make sure the filler is "level". i.e. feathered into
the surrounding area w/no bumps. My work felt ok, but the top coat is
oh so revealing...... oh well it's not too bad.
