Questions about primer finishing before painting

So obviously I have some orange peel to my epoxy primer I laid on. I am using it as the filler primer as well, its not EASY to sand as the label said, but after a couple days of drying its not bad. I block sanded it with 220 then put on another coat and would like to go straight to wet sanding. I only have 2 weeks till I have to leave to go back to school and am trying to save some time to make sure I get things done. At the same time I donít want to half *** it.

Does the primer need to be perfectly flat and consistent? I mean the orange peel. It doesnít take much to take off 99% of the orange peel but then there are some crevices left that look kind of like really shallow pin holes, the bottoms of the orange peel. I did some more sanding and it takes quite a bit more sanding to completely eliminate them. Obviously it would be a big time save if it isnít necessary to do this. They cant be seen from more than a foot or 2 away, so I donít think they will have any effect on the final job but I want to be sure.

Also I was wondering about how much the color of the surface is going to matter. I am using a grey epoxy primer and am not going to use a sealer. If I donít prime the door jams or I have a couple of sand throughs to the original paint is it going to be noticeable in the final job? I plan on using 3 coats of base before clear and the origoinal paint is the same color i will be painting it (red)

the flatter and better your sanded primer looks, the better the end result will be. as for the door jambs depending on your paint it will be harder to cover the "break through" spots and the color differance between the primer and the original color. solid red is a forgiving color as far as some imperfections. if it were my car i would take a poly. putty and fill the pin hole like low spots. wet sand then seal the entire car and then color and clear. jusst my 2 cents.
