Frustrated with inability to do body work!

First let me say thanks to so many people that replied back to my post. Many great suggestions and tonight I went back to work on it. I think things went very well tonight as I had a different mind set to attack it with. So here is where I finished up tonight.

I spent 1 1/2 hrs tonight and felt as tho I made more progress then all my other nights combined. The biggest thing that kept running thru my mind tonight was to not rush it, dont take off to much at one time. So I sanded with a lot less pressure and was in no hurry and I think I made good progress. A few people threw out that need for primer last night. So my question is am I ready for primer? Also someone mentioned using an epoxy primer. Do I spray that before I used a high build primer or after. Last fall after I sanded the entire car to bare metal I just sprayed it with the high build primer. Now Ive had it covered with plastic since then but I did not use an epoxy primer on it. Does the high build primer have a shrink factor and how long after I spray that can I sand on it? If I need more filler once primer is on do I need to sand first or just apply on top of the primer? How many coats of primer can I put on and how much fill will it do because the 80 grit leaves sand marks. DO I sand with 180 before priming?

Again thanks for all the comments last night and feel free to add more tonight. I wont be able to work on it again now until Monday night. Thats one of the biggest problems I have is finding time! But I will be working more on this since fall is just around the corner and I would like to paint this fall before it gets to cold.
Thanks Again and feel free to comment. You wont hurt my feelings if you see something.
Thanks Rod
