You can't sand anything next to the foam without messing up the foam. If you have small voids near the edge it's best to leave them a bit depressed when filling with micro or at least squeegee them smooth before the micro sets up. Do the final fill with micro when doing the glass lay up and squeegee the spot smooth. Any glue at the edges or on a glue line that sticks up above the foam should be cut back to the edge or a "V" notch on a glue line using a razor blade or similar tool. It will only take one attempt at sanding he glue down to learn the lesson. If you have an area that needs significant attention, cut out the foam, insert a new block, and start over. The hard shelling worked great for me but do a couple of small test blocks for yourself before applying the process to your project. Compare the couple of processes and see how they work for you. Six inch squares are large enough for a test. Hard shell one block and do the other with the seal and glass at the same time process. Go the route that you feel comfortable with. Larry Flesner
