Another update:

As mentioned, i still had a few inserts to level.. these inserts i decided to try filling them with acrylic lacquer, but this time i removed them from the pf to do it! Basically i did the same exact thing as with the arrow inserts, ie spray acrylic on to fill and sand, fill and sand etc, until flat. It took about a day and a half to do it while waiting for lacquer to dry so i could sand, but it worked out pretty well. To sand them i placed a sheet of 800 grit wet&dry on a flat surface, sprayed on some Windex, and sanded until the black on the outside edge just started to disappear, then i would clean with Prepsol and respray more acrylic on and let them dry again. i did the several times until they were completely filled and flat. after that i gave them a sand with 1200 grit and finally a polish then installed them.

pics were taken half way thru the process, and you can still see the low spots.
