I have sanded filled and sanded. After sanding the filler there were more caracks! If I tryed filling and sanding again I will have new places to fill! So that being said I did my sealer coat. It filled some of the cracks but not nearly all! One large crack the epoxy ran through the hull. Epoxy will not run through now. Most of the the cracks are less than 1/32 wide. Should I do a second sealer coat or should I glass next. Will glassing leave voids at the cracks?

thanks.
