Since I've never done this before I'm guessing about when to stop sanding the epoxy fill coats.

Seems logical to run the ROS until all the shiney spots are gone. Obviously there is more epoxy in some places than others and the shiney spots aren't all gone when you start to hit glass.

I assume that seeing that weave is the indicator of when to stop sanding? The pic attached shows what I've got going in a few places. Weave showing while there is still untouched epoxy. Not entirely unexpected, of course.

So, does that look about right or if I hit the 'glass have I gone a bit too far?
