: matter what I did I couldnt get rid some very small bubbles in the epoxy
: filler coat.I was going to clear coat with auto clear after.Should I sand
: and clear or do I need to remove the bubbles?

You have a few options here:
1. Apply another thin coat of epoxy. Do it when the temperature in your workshop is *falling* and take extra care to remove any visible bubbles with foam brush while the epoxy is still wet. You may get a fairly bubble-free surface.
2. Sand the current epoxy a bit-just enough to not reveal the fiberglass weave.
It won't rid of all the bubbles but at least the worst ones.

When you get to this point check how bad the bubbles are.
- If they are not too bad you can finish your boat with varnish or another clear-coat finish. Varnish will cover the minor bubbles.
- If bubbles are still bad, just paint the boat with paint.
