heres the flat spots I referred to before...they were actually caused by a high spot in the filler...got some soft sander pads that allow for a flexible but firm sanding backer... they work very good..
after a little sanding you can easily see what caused the flat spots..

I'm putting this up for people like me that have never done this before
pic 1 is the soft sander pad
pic 2 shows sandpaper layed over the radius.sticky side up
pic 3&4 shows the soft sander stuck to the sandpaper and how it holds the radius
pic 5 shows the high spot in the filler that in turn was making the flat spots I could see
