STRINGER DISASTER

i RECENTLY SHAPED A FEW BOARDS 2 OF WHICH ARE GLASSED AND IN THE WATER THE THIRD IS STILL IN THE SHAPED STAGED AND SITTIGN IN A RACK. THE 2 BOARDS HAVE COME UP WITH A STINGER THAT IS HIGHER THAN THE FAOM AFTER JUST A FEW WEEKS. I CAN’T THINK OF WHAT THE PROBLEM COULD BE SINCE THE ONE THAT IS SHAPED AND HAS NEVER BEEN GLASSED OR EXPOSED TO WATER IS DOING THE SAME THING. HAS ANYONE EVER HEARD OF THIS HAPPENING AND IF SO WHAT IS THE CURE OR WHAT PRECAUTIONS NEED TO BE TAKEN?

THANK YOU FOR ANY SUGGESTIONS.

What kind of foam are you using? Are all three shaped from the same foam? I remember a discussion not too long ago about foam collapse, but i’m not sure this is what is happening. Some pictures would help.

Oh, and stop YELLING.
