I finished glassing and epoxying my hull some time ago, though additional sanding and probably another coat is required. When I was takinga break and just looking at my hull I found a large elliptical bubble - maybe an inch and a half by 2 inches.  I assume I need to cut it out, reglass and blend it in to the existing.  Any  tips on the best way to get the bad piece out and complete the repair?  

I also have a void where the glass is wrapped around the bow.  When I was laying the glass I did my best but obviously fell short.  My choices seem to be to either cutting out the glass and trying again, which, at least at my skill level I think would be quite challenging, or just pouring some unthickened epoxy into the void - probably at the same time that I do my end pour.  The void is perhaps an 1/8th in at the top and then tapers down - that may not be terrible but it does flex a bit under finger pressure.  Any thoughts?

Thanks
