Frustrated with inability to do body work!

Had an opportunity to go out last night and do a little work. I decided to throw some primer on the front fenders just so I could see what the lines looked like. Here are some pics of each fender. Im not satisfied with the lines so Im going to try to get them a little straighter and a lttle more level. I can see that the holes I welded were still a little low.
Here is the passenger side, the one thing I see is each spot that has filler on it bleeds thru the primer. Its only one coat but is this normal?

Now here is the drivers fender. same thing I can see a bleed thru of each spot that has been repaired. The lines are the only thing i was not happy with. I think the other holes that were welded and repaired are good.

Now I must tell you these fenders were only sanded with 80 grit so far. I guess now as I go forward I will need to go to a 180 grit. Maybe thats the reason that the repaired areas look the way they do? Also i wasnt real concerned about dirt so I didnt clean before I sprayed figuring I would need to sand anyway. I was just trying to get an idea about where I was going to be in the repair process.
After I was done I did a quick soft sand across the line area and found that I had low spots so I put a little more filler on the entire center line area and left it sit over night. I will try to get time tonight to address that area again and see if I can improve that. Let me know your thoughts and where you think I should go next to make this better.
Thanks Rod
