Thanks guys! I'll ask one more question but I think I know the answer. Somehow, I've ended up with several spots where the resin pooled in the bottom causing raised "bubbles" of resin. I did not notice them until I put the second coat on for some reason. My light must not have been good enough to expose the areas until they got shiny again with the second coat. Anyway, it looks pretty bad but I'm willing to live with it unless there's an easy fix. The way I see it, I would have to sand down the raised areas, thru the glass because it also lifted in some spots and patch those areas. I'm not sure it's worth it. I don't see that it would structurally be an issue?
