What grit of paper did you finish the filler in (if you used filler) before you applied primer?
I'm rereading your post and a step by step analysis of what you exactly did would help. Not only the proper way to repair the area but, if an error was made, so that we can correct it for you and explain what happened.
This is how I bought it. Primer over a little bit of body filler. It wasnt that much body filler. The car wasnt dented, but more scratched from someone hitting a guard rail.
I only put some "red lead" filler in small chip parts.
I re-primed it and sanded with 180 (only the parts in primer in picture). Then I re-primed it a week later and sanded with 320; again, only the parts in primer in the pic.
I then sealed the primer parts.
I sanded the whole fender and door with 320. I had to get the old clear coat off because it had bubbles/bumps in it like someone had water in the compressor when they sprayed the clear.
I waited 2 days to put base coat on.
Door came out fine, no scratches.
Scratches in fender appeared over sealed areas.
That takes me today where I sanded whole fender with 600.
Then primed the parts that were scratched again, wet sanded with 600 after it dried for an hour.
Now its worse in some spots and better in others...
Again, car needs to be totally redone (note the bubble on the quarter, ect) It looks much better than it did, just up close you see the sand paper scratches. Running low on paint and dont want to waste more money, so need a quick fix before clear coat.
