Don't you need hardener Jeff, to mix with resin for doing this kind of
repair?

Without stating it I think Jeff was referring to a resin mix of part one
and part two or whatever product you're using that would make a bonding
mix. Just using one part of a two part mix would do nothing for adhesion.
Here is a copy of the post I sent to MR. Goodnight off line.
Robert,
Without seeing the defects I'm guessing they are not a problem. Many
KR's have experienced them. Common belief is they are caused by
"out-gassing" of the foam and causing the glass to de-laminate from the
foam. That is not really a structural problem if it is only over and
area of foam. I had a few appear on mine years ago and they
disappeared. If concerned, or if you just want to get rid of them,
consider putting a pin hole in the bubble and they may go down. You
might also want to put a slightly larger hole in the bubble large enough
to inject some resin under the skin and weight it down till the resin
cures.
Keep on keeping on....................
