Foam repair, advice pls

Hello,
Got two old (roughly 15yrs) foam surfboards out the in-laws shed the other day. One is in a bad way but hoping to repair. Can anyone recommend how to deal with any of the following issues:
- large bubble between slick underside and interior foam
- cracks / chips in slick
- crack in foam trimming (connecting slick to main body foam)
- trimming peeling away from slick and main body foam exposing interior
Having had another look it may be too big a job, which is a shame as the foam is in excellent condition considering its been in a shed for over a decade.
Any advice would be greatly appteciated. I will also post looking gor advice on the ither board which is in much better condition.
Many thanks,
Aaron
