How to prep for flow coat ( tight spots)

I got the shell of my car sanded with 400 and then hit with 600. What do recommend for the door jambs and in drip rail areas that are hard to get sand paper in? Can I wash the car with dawn detergent and a scotch pad, gray or red?
 
I prefer to have sanding sponges on hand for that application because they will reduce texture while gray pads won't. Gray pads are useful for eliminating little remaining shiny spots, though. Here's what sponge we use:

If you can't flatten an area there's no point in recoating it. Make some small blocks for the jambs, or use the sanding sponges like Crash suggested. Plastic filler spreaders cut up make good little blocks, are flexible as well. Paint sticks cut up and acrylic sheet are two other options.
 
You're not likely to do much sanding in that area, so it will be a lot of build up. If you do try to do a proper amount of sanding, you will likely sand through on some of those edges.
If you don't do a certain thing, then you will never get good at it. Try to get good at masking.
I do a lot of masking at work, it's just something I try to avoid if I can.

I do a lot of masking at work, I just don't seem to get any better at it.
