small crack on bottom of 250 x ican see the fiberclass its the size of a quarter , whats thebest to use to repair it

Duraglass will do the trick. Make sure you prep the area well and that it's dried out completely.

yea i put it on and it came off i think the hull isnt dry , what should i use to dry it out

A hair dryer or heat gun.....and time. The surface must be clean and rough so the Duraglass adheres to it.
